Steam seems to suffer from the issues of discovery of great content among the sea of average stuff. That's a different, common and hard to overcome variant of enshitification.
It's true that Steam pushes big-name AAA games, but Steam still regularly shows me incredible games I've never heard of without me prompting it to. As someone who browses game forums frequently, I'm amazed at that. The bigger problem IMO is just the insane oversaturation of video games. Even if I quit my job and all my other hobbies, I would never catch up to all the games I want to play. So I don't think it's even possible for Steam or another storefront to nail discovery in a truly satisfying way.
This is true -- there is a lot of dross and spam on Steam -- but there is also a whole galaxy of game reviewers, curators, and commenters. It's not hard to find a few and follow their advice.
Meanwhile, no one is reviewing all of the cheapo garbage on Amazon. 44 different drop shippers all selling stuff from China, and all without any meaningful way to differentiate them. Hell, they could all be the same company.
