I can get behind that, agreed. It's misleading and to be honest it is rather two-faced of the publishers and studios. On one hand, they tell us those deals are good for everyone and there is nothing wrong with them. On the other hand, they play coy and try to stave off the exclusivity announcement as long as they can, which shows that they know full well what's wrong with it.Personally, part of a problem to me, is that all of these games are advertised as being released on Steam, Valve dealing with this BS would be enough for me. If the game is announced as EGS exclusive since its inception it's much easier to forget about its existence.
Edit : Ascheroth made a pretty great point about the practicality of enacting this with late-stage moneyhats, I agree with him.
