I've occasionally seen #Steam rattled off as an example of "enshittification"--it gets a mention in the blog post coining the term, alongside obvious examples like Google search and Amazon.
Has the Steam user experience deteriorated that much? Maybe I just haven't been playing as many games out of the Steam launcher lately, being focused on things like MTG Arena and heavily modded X-Com, but I haven't noticed a downward spiral. Hasn't e.g. the Steam Deck been a genuine/deserved success?
