Magnitus: The few people who are affected by this and are unhappy about it have nobody but themselves to blame. You decided to make some corporation your daddy whose permission you need to ask to play and enjoy your games. You made your bed, now kindly lie in it.
While I agree with you on this, I think we can bring a bit of nuance: I suspect that only a fraction of Steam users know what DRM is, a fraction of that fraction knows that DRM is not a fatality, that DRM-free games are a thing, and a tiny minority of them knows that DRM-free multiplayer is a thing too (on this last part, GOG customers are barely better informed, sadly).
So they agreed to a very anti-consumer contract, but most of them probably did it out of ignorance, not out of carelessness. In my opinion, only those who did it out of carelessness really deserve what you wrote ;)
That being said, I too like that Steam (and DRM/vendor lock-in actors more globally) show their true face more often. People need to understand what the true goal of DRM really is: that it is
not related to piracy, but is all about corporate control over their customers.
