U.S. lawmakers have reintroduced the bipartisan Open App Markets Act, aiming to curb Apple and Google’s control over mobile app stores by promoting competition, supporting third-party marketplaces and sideloading, and safeguarding developer rights. AppleInsider reports:

The Open App Markets Act seeks to do a number of things, including:

• Protect developers’ rights to tell consumers about lower prices and offer competitive pricing;
• Protect sideloading of apps;
• Promote competition by opening the market to third-party app stores, startup apps, and alternative payment systems;
• Make it possible for developers to offer new experiences that take advantage of consumer device features;
• Give consumers greater control over their devices;
• Prevent app stores from disadvantaging developers; and
• Establish safeguards to preserve consumer privacy, security, and safety.

This isn’t the first time we’ve seen this bill, either. In 2021, Senators Blumenthal, Klobuchar, and Blackburn had attempted to put forth the original version of the Open App Markets Act.However, the initial bill never made it to the floor for an office vote. Thanks to last-minute efforts by lobbying groups and appearances from chief executives, the bill eventually stalled out.

While the two bills are largely similar, the revised version introduces several key differences. Notably, the new version includes new carve-outs aimed at protecting intellectual property and addressing potential national security concerns.There’s also a new clause that would prohibit punitive actions against developers for enabling remote access to other apps. The clause addition harkens back to the debacle between Apple and most game streaming services – though in 2024, Apple loosened its App Store guidelines to allow cloud gaming and emulation.

There are a few new platform-protective clauses added, too. For instance, it would significantly lower the burden of proof for either Apple or Google to block platform access to a third-party app.Additionally, it reinforces the fact that companies like Apple or Google will not need to provide support or refunds for third-party apps installed outside of first-party app marketplaces.
