Apple’s App Store Under Fire: Global Rulings Open the Door for Fintech Innovation and Raise New Cybersecurity Challenges¶

Apple app store, judge, fire

In a historic shift for the digital economy, Apple is being forced by courts and regulators in both the United States and Europe to allow app developers to use any payment method for their apps and in-app purchases-without Apple’s customary commission or fees. While these rulings are set to unleash a wave of fintech innovation and competition, they also introduce new cybersecurity risks that could impact millions of users worldwide. This article explores the legal battles, the global regulatory landscape, the opportunities for fintech, and the security challenges that lie ahead.

The U.S. Showdown: Apple’s App Store Monopoly Challenged¶

Apple’s legal troubles began in earnest in 2020, when Epic Games, the creator of Fortnite, sued the tech giant over its App Store policies. For years, Apple required all digital payments on iOS to go through its own system, taking a 30% cut-often called the “Apple Tax”-and forbidding developers from steering users to alternative payment options.

After a lengthy trial, U.S. District Judge Yvonne Gonzalez Rogers ruled that Apple’s anti-steering provisions were anticompetitive and illegal under California law. The court ordered Apple to let developers include links to outside payment platforms. Apple, however, responded with new barriers and a 27% commission on off-app purchases-moves the judge saw as attempts to protect its lucrative revenue stream.

On April 30, 2025, Judge Gonzalez Rogers found Apple in wilful violation of her previous order. She ordered Apple to “immediately cease obstructing developers’ communication with users and cannot impose its new commission on purchases made outside the app.” The judge also referred Apple to federal prosecutors for possible criminal contempt, citing evidence that Apple executives lied under oath and concealed documents.

Europe Steps In: The Digital Markets Act and Apple’s EU Reckoning¶

Apple’s App Store practices have also come under intense scrutiny in Europe, where the European Union’s Digital Markets Act (DMA) became law in 2024. The DMA targets “gatekeepers” like Apple, Google, and Meta, imposing strict obligations to ensure fair competition.

Under the DMA, Apple must allow app developers to:

Inform users about alternative offers and payment options outside the App Store
Direct users to those external offers
Enable purchases via alternative channels without undue restrictions

Despite Apple’s claims of compliance, the European Commission found the company in breach of the DMA’s anti-steering obligations. In March 2024, Apple was fined €1.8 billion after a probe triggered by a Spotify complaint over music streaming competition. On April 23, 2025, the Commission fined Apple an additional €500 million for continuing violations, ordering the company to remove restrictions and refrain from similar conduct in the future.

The EU is also investigating Apple’s new contractual terms for developers, including a €0.50 fee per app download outside the App Store and the user experience for downloading from alternative stores. In a separate case, Apple settled an EU antitrust probe by allowing payment rivals access to its NFC technology, enabling banks and payment providers to offer “tap and go” payments on iPhones.

The Commission has warned that Apple could face fines of up to 10% of its global revenue if it fails to comply fully with the DMA. Apple continues to defend its practices, citing security and user protection, but the EU insists that consumer choice and fair competition must come first.

Fintech’s Golden Opportunity: A New Era of Payment Innovation¶

These rulings crack open the gates of Apple’s walled garden, allowing any payment provider-whether established giants or nimble fintech startups-to compete for billions in app and in-app transaction volume. Companies like PayPal, Stripe, Square, Adyen, Braintree, and global card networks such as Visa, Mastercard, and American Express now have a direct path to offer their services inside iOS apps.

Spotify was among the first to take advantage, quickly updating its app to show clear pricing and direct purchase links, bypassing Apple’s commissions. Epic Games is planning Fortnite’s return to the App Store, now free to use its own payment systems.

The potential impact is staggering: Apple’s App Store developer billings reached $1.1 trillion in 2022, with an estimated $100 billion previously subject to Apple’s commission. Now, that revenue is up for grabs, and payment companies are expected to roll out new features, better rates, and innovative financial products to win over app developers and users alike.

Cybersecurity Implications: Innovation’s Double-Edged Sword¶

While the rulings are a win for competition and consumer choice, they also bring some cybersecurity challenges. Apple’s tightly controlled payment system enforced uniform security standards, but the new open model means security now depends on the practices of each payment provider and developer.

Key Risks¶

Fraudulent Payment Apps: Less reputable payment providers could expose users to malware, phishing, and data theft.
Data Breaches: Third-party processors may lack robust security controls, increasing the risk of breaches and leaks of sensitive information.
Phishing and Social Engineering: More payment options mean more opportunities for attackers to trick users with fake payment pages or deceptive prompts.
Weak Authentication: Not all providers enforce strong authentication, making accounts easier to compromise.
Insecure APIs: Poorly implemented integrations can be exploited to intercept or manipulate transactions.

Three Threat Scenarios: How Open App Payments Could Expose Users to Cyber Attacks¶

Here are three relatable threat scenarios that could emerge from opening app payment systems to third-party providers:

1. The Fake "Discount" Payment Pop-Up¶

Scenario:
A user plays a mobile game and sees a pop-up offering "50% off in-game currency if you pay now!" They click the link, which redirects them to a payment page that looks identical to Apple Pay or Google Pay. The user enters their credit card details, but the page is actually a phishing site run by scammers.

Why it works:
Fraudulent developers could create fake payment screens that mimic trusted services. Without Apple’s oversight, these scams could slip into apps, tricking users into handing over financial data.
Example: A 2025 report found cloned payment pages mimicking PayPal stole over $2 million from gamers in one month.

2. The Coffee Shop QR Code Switcheroo¶

Scenario:
A coffee shop uses a third-party payment app for loyalty rewards. Hackers replace the shop’s QR code at the register with their own. Customers scanning the code to earn points unknowingly send payments to the hacker’s account instead.

Why it works:
Open payment systems allow apps to use unvetted QR code providers. Criminals exploit this by hijacking codes or creating fake ones, as seen in a 2024 attack on small businesses in Europe.

3. The "Romance" Subscription Scam¶

Scenario:
A user meets someone on a dating app who convinces them to upgrade to a "premium membership" for better matches. The link directs them to a fake payment portal claiming to use "SecurePay." The user pays $50, but the subscription never activates-and their card is later charged for unauthorized purchases.

Why it works:
Scammers use social engineering to create urgency or trust. With no Apple-mandated fraud checks, malicious apps could easily host fake payment gateways. In 2025, romance scams cost victims $300 million globally, many through in-app payments.

Why These Matter:
Opening payment systems removes Apple’s "gatekeeper" role, shifting security responsibility to developers and users. While this lowers costs, it also creates opportunities for bad actors to exploit gaps in oversight-a trade-off highlighted in recent EU and U.S. rulings.

Industry Response and Best Practices¶

Payment companies like PayPal, Stripe, Square, and others must prioritize security to earn developer and consumer trust. Compliance with standards like PCI DSS, robust encryption, tokenization, and advanced fraud detection are essential. Developers should vet payment providers for security certifications and implement multi-layered security, including regular audits and strong authentication.

As the payment landscape fragments, both developers and users must become more vigilant. Developers should select reputable, security-focused payment partners, and users should be wary of unfamiliar payment options and remain alert to potential scams.

Apple’s Greed Backfires¶

Apple’s relentless pursuit of fees-even after being ordered to stop-ultimately brought about this sweeping change. The court found that Apple not only tried to sidestep the injunction with new fees and “scare screens” to deter users from leaving its ecosystem, but also concealed its actions and misled the court. As Judge Gonzalez Rogers put it, “That [Apple] thought this court would tolerate such insubordination was a gross miscalculation. As always, the cover-up made it worse. For this court, there is no second bite at the apple.”

What’s Next? A Global Precedent¶

Apple has said it will appeal the U.S. ruling, but must comply with the court’s order in the meantime. The decision is expected to reverberate beyond the U.S. and Europe, as regulators worldwide scrutinize Apple’s practices and push for greater competition in digital marketplaces. The UK and China are closely monitoring these developments and may follow suit with their own regulatory measures.

For fintech firms and developers, this is a watershed moment: the end of Apple’s gatekeeping over app payments, and the dawn of a more open, innovative, and competitive era for digital commerce. But with this freedom comes new responsibility-every participant in the payment ecosystem must now work harder than ever to keep users safe.

The battle over App Store payments is far from over, but one thing is clear: the days of Apple’s unchecked dominance are coming to an end, and the world of app payments will never be the same.
