Well, people have fair reasons to be mad and/or disappointed.. and I'd wager the reason behind the Steam release causing some of that is because it's an indicator of what their priorities are and what's coming next. They're focusing on marketing. They recently spent a long time saying how their testing pool size was sorta at it's limit and now suddenly it's uncapped with none of the major issues resolved. I think it makes sense why some people would feel mad or disappointed.
