As a long time Steam user, while I still really like Steam and think it's the more consumer friendly platform, it has devolved greatly. Especially discussion forums are nearly no different than reddit toxicity where people exhibit their worst behaviors. I miss the legitimate discussions and love for specific games. Now it's mostly complaining and complete disregard for developers being humans.
The flood of garbage games has also been fairly obvious over the last decade. Some filters on your account handle a lot of this at least for the adult ones, but not all of it. It reminds me of the Wii shovelware era, but far worse.
