Competition is key though. Plenty of publishers know that ditching established installers and app stores comes with a price, and so publishing or at least co-publishing on steam/epic/gog/etc is pretty important.
And the consumer experience isn't great when jumping between games during the day means opening 3 different launchers and having them constantly run in the background if you don't manually close them.
I've said this before: if Epic wins the lawsuit, you're going to either see the Epic launcher show up on Xbox, Playstation, and Switch or Epic's going to 'negotiate' with those publishers to get an extra 15% (or more) cut of sales.
I’d rather have that than the current situation on mobile where because of the 30% cut, every game is littered with ads or pay to win tactics to increase their margins. The situation for games on desktop and console and handheld portable consoles is leaps and bounds better than mobile.
I don’t see how a launcher would need to be allowed. Only a new store to purchase. Xbox, PlayStation, etc. could have some policy still that says that when you launch a game it must not spawn any persistent background service or that it must launch directly without a launcher.
