...I think all of you guys are missing the point.
I'm not worried about being SUED because I didn't have the chance to read part of an EULA. (Yes, I know the thread title gives that impression... but that's a secondary issue to me. The legal part seems to be the most interesting aspect of the situation, but it's certainly not the one that worried me the most.)
I'm worried about my data being sold on the open market because I installed something that uses targeted ads as part of its service, but doesn't say a thing about what data it's using or how it's using it.
This isn't a legal point. This is a "I don't have a clue what these guys are doing with my data" point. For all I know, they could be sending records of everything on my computer to a dozen advertising firms. (Yes, this has happened before with other games.) That's not something I'm willing to agree to - legal or not.
And I get that you don't need "gamespy comrade" to play the game, however there's nothing in the documentation of the game that actually SAYS that. The EULA specifically states that you need to install it. If that's wrong, great! Unfortunately the games company didn't say that, Steam Support didn't say that, and now it's irrelevant anyway (I've already got a refund for the game).
