Right. See, you think that list of bannable reasons at the end is making this sound less dystopian and DRM-abusive and stuff?
It's kinda doing the opposite.
Don't get me wrong, most of those are scummy (not sure about the account sharing one, though), but in real life you at best get fined or banned from a store or something. Nobody comes into your house and sets your 20 year old game collection on fire for being a bit of a dick.
Which, hey, whatever, I don't expect my Steam account to get banned any time soon. But the EULA is very clear that none of those games are a thing that I own and I don't get to give them away and people don't get to inherit them eventually and if they DO decide I'm a scumbag those games are gone.
And that sounded quaint and hypothetical in the early 2000s, but dude, that account is a significant share of my assets by now. If I had bought all those games physically I could live on reselling them for months.
