Not to mention their role in you not owning your games.
I do use Steam to "purchase" games, and it irks me that they're still allowed to show "Buy" when in reality you're essentially leasing/renting the game, can't believe it's legal for them (and others) to trick people like this still.
In a previous timeline, this has led to me going on ebay to find CDs of a long lost game (EarthSiege 2), which I promptly uploaded to the Internet Archive as the one distributed by the current license-holder at the time had an older, unstable version with bugs and, more importantly, no audio and my own original copy got damaged to hell and beyond...
Don't get me wrong, as mentioned, I use Steam and like Steam/Valve, but that move is a bit shitty regardless.
