Frankly, I despise all launchers, Steam included. The only reason it gets a pass is because it's one of the two somewhat reasonable ones, and the only one that makes gaming on Linux simple and convenient.
It's still slow, ugly as hell, and entirely unnecessary. Makes me want to pirate more, but then I'd have to set the games up from scratch.
The only use case for launchers is console gaming. It makes perfect sense on a Deck, Switch or a PS5. But absolutely no sense whatsoever on a desktop PC.
Again - Steam has features that make it tolerable (achievements, screenshot sharing, workshop, etc.), but I'd still prefer to just play my games without anything in the middle.
