I don't think so, at least not as a consequence from this case if Apple loses. Antitrust cases are usually very limited in scope. Microsoft's loss required many actions (documenting Active Directory and other protocols/formats, browser choice screens, etc.), but no one else in tech were required to do so.

John Sircacusa (from ATP.fm) pointed out years ago that the heart of Apple's biggest issues is business relationship management. This was when Apple only had a handful of issues with a few companies and made some poorly received statements about developers. Their ability to build mutually agreeable relations has only gotten worse in recent years.

Sony and Microsoft have kept their relations with third parties tough but ultimately agreeable. They promote practically all of their third parties (unlike the App Store which has so many apps that its like winning the lottery to be promoted). Consoles have stores which are probably more curated but which third party publishers/developers actually like.

IMO, DoJ, EU, etc. are acting primarily because they have received so many complaints from Spotify, Microsoft, Epic Games, Google, Meta, Tile, etc. Governments don't take action for the "public" interest on its own.
