So, you are an ex-Steam employee looking for some payback or what?
I don't buy it. If you make a good game you can tell Steam to shove it, if you want to. Minecraft being an excellent example of success without Steam -- although I don't think Persson was purposely flipping the bird at Steam.
I suspect you'll find more Indie devs. who appreciate the pluses they get from Steam than ones who hate it for all the restrictions created by them. However, even if I'm wrong -- it's clear that Steam isn't required for success. Only having a good game is.
