I like Steam/Valve but I do rather agree with some of these points. If I recall correctly the Steam store has "Buy" buttons instead of "Subscribe" or "Add Subscription" buttons as well.
I'm pretty sure I have seen people mention this mutliple times, so I got curious enough to check. Origin license agreement:

Subscription/license stuff aside (not sure if it's comparable to Steam), where in there does it mention lawsuits, class action or otherwise?
For that matter, can you link me to at least two other services' license agreements that do have class action options, since you said that all the other services have them? (even GoG?)
