You don't side load games onto your PC from Steam. You don't side load games you got on disk.
You fucking install them.
That's what you did with Palm Pre apps, that's what you do with Linux apps, windows apps, Mac apps.
It's only Apple and Android phones that are exempt.
Fuck you for keeping this I play. Fuck the people who don't think it's a problem. And fuck you for not being loud about it to whatever half assed politicians you can make miserable.
