I think you have underestimated the amount of junk is actually on Steam. You obviously haven’t looked at the later pages of Steam Charts to see the thousands of games that have extremely few to absolutely zero players.
The only reason Steam has less junk than itch.io is because of the higher barrier to entry: You have to pay ~ 100 dollars to just get a Steam page.
plus, that $100 steam fee gets you a lot. So much that it's almost charity how they promote your game. I'm dead serious, they actually want to see you succeed so much that it makes the admins of this site look antagonistic by comparison. You get exposure by doing nothing on Steam, whereas here you get... well, nothing, you're at the mercy of the staff who curate this site, unless you happen to be making a generic streamerbait horror game as I have already stated.
