I don't think that's what's going to actually happen. In the same way that Bluesky is replacing Twitter while Mastodon comparatively languishes, whatever decentralized way of distributing games we might hope for is just going to get beat out by Epic or whatever next launcher shows up, assuming these rules don't become reified as actual laws. Creators will still just be in a situation of making a game that plays by all these rules, or languishing in obscurity. And that's assuming Steam even loses its grip, I'm not holding my breath on that. I think it's much more likely they just keep dutifully enforcing these bans, and the vast majority of people simply don't know about it or don't really care unfortunately.
