>Steam on Linux
It's cool it exists and I don't care if it's closed-source, proprietary, whatever. I'd rather have Linux ports than not.
But the fact Steam is the "okay" launcher/DRM/bloatware on PCs to begin with has always rubbed me the wrong way. People complain about all the others ... but Steam is fine? I remember buying games on discs and the Gamespy stuff was effectively opt-in adware in the installer. Imagine you needed it just to play.
Get rid of DRM, even if Steam exists as a marketplace, allow people to just install the games and run .exes for the games they've purchased without running the client. It's absurd to me PC gaming ended up this way.
