This means, if you ever have a PayPal-froze-my-account issue, you are guilty of Fraud, and thus they take back all your bought (Erm, rented?) games.
This is something I do not like and that always gnaws at me about the platform. Especially combined with their very poor customer support. ( Approaching Google-level of user hostility )
- need to be single-user admin with saved password
- didn't know that before? tough! you're locked out from all games including DRM-free ones
- happened again and still can't get offline mode? tough!
- support limits how big a message you can send so I couldn't send complete info (not that they looked)
- support promotes racial hatred, closing issue with poor English and telling me I didn't do what I did.
- follow up support also closed.
- considered small claims court but was convinced it really wasn't worth it.
lesson learned: There is no such thing as "friendly" DRM. When the system decides you are wrong, there is no recourse
 Unless you're a famous blogger, have a personal contact or other out-of-band means unavailable to the masses.
In my experience the steam client is physically painful to use (unpausable downloads, cache verifications, slow startup, unresponsive store). It's not as bad as iTunes, but it's getting there.
