I noticed that about TOSes, and, in fact, I've started doing just that. Last year, I spent over $1200 on gaming, both PC and Console (and none on credit, to counter the inevitable trolls).
This year? $140.
I've already decided I'm finished playing the console game, now that all three console makers are playing the stupid Sony bullshit, of forcing potentially console-crippling updates to be installed before playing games that have nothing to do with the console's dashboard software.
I passed on Skyrim because of the steam requirement, which puts me under Steam's TOS even if I buy the boxed version, too. I get the feeling that by this time next year, I will, in fact, be finished as a gamer.
Look. Despite what I have been posting, I am NOT a Steam fanboy in the slightest. I'm very partial to the idea of having control over my own software, and am definitely not a fan of basically what we're getting with Steam and Origin - a perpetual rental license that is tied to a single account, which if compromised or otherwise goes against the ToS for whatever reason, could result in a total blocking out of the software you and I paid money for. It's insane!
And yet... not enough people seem to be complaining. Dissenting views like yours are far and few between these days, and it's a concern as well because it means that people have either given up trying to get anyone to listen to them about these very legitimate concerns, or they're too young/ignorance to have the foresight to care.
So what does someone like me do? Well, I've tried the Humble Bundles and there are a lot of good games there, but I've noticed indie games generally don't seem to have the lasting appeal that bigger budget titles from professional publishing houses have (not all of course). So I find myself caught between two sides, and I guess I felt that to get the Deus Ex'es and the Skyrims and the other games that people play and talk about, I'd have to suck it up and live with it. Because it's not getting any better it seems.
Though maybe your solution of giving up gaming entirely is better. It is a healthier option after all. :) I just wish more people had these concerns, or at least expressed them. We are gaming pariahs for disliking Steam basically, and hence aren't listened to. I just don't know if I'm prepared to give up gaming. I'm not principled enough, so I console myself with these logical facts to try and make things like Steam more palatable, in case the worst does happen.
