Mark my word, once Gabe pass it's gonna be very very different. We have very different things to worried about, like climate change, but on software side and tech we shouldn't rely on monopolies. Valve was kept in that state because all the competition didn't actually put up a fight worth extra investment. The windows store pushed valve to develop SteamOS and Proton, they also back off on some revenue split policy because of EGS's deals. (Let's be honest, not all players care about which launcher they use, as long as they get better deals and can play the game they want.)

And to my experience, Steam's recent years' updates to store/client are not something I like as well.

• I don't like the gamification of sales event etc.
• I don't like the new unlimited scroll type, they backed off a bit and become like 3 pages long until you hit the top/popular/sales part.
• I also don't like some of the UI changes(ie the downloads/library mixed together and not separate item)
• I hated the auto start live streaming thing, if there is option to turn off that please let me know.

For EGS,

• their search sucks
• library page sucks, you can't really organize your free games/purchased games etc.
• auto updates are pretty on par so that's okay.
• their friends/etc also sucks.(not that I care much but at least it's far worse than steam one.)
• I like that they adopted Nintendo's gold coin reward type to encourage consumer to purchase there.
• games from other big publisher usually do require install their clients as well, which sucks. (it's similar on steam as well.)
