Aside from not liking being dependent on a internet connection in the first place and tinfoil hat stuff, it was doing something weird with a partition on my old computer so I just disabled the whole thing and didn't look back.
Bruh, I hate "The Cloud" meme that businesses love today, I selfhost everything I can, but Steam really is a 'Cloud" business. Lots of other people's computers used to store and distribute video games via a custom application.
