From the looks of it, it's a combination of misunderstanding (devs could've been clearer, people could've read the fine line more) and some systems still being remarkably broken in multiplayer.

I don't think the devs should be given as much shit over it as they are, since I doubt it was with entirely malicious intent, but they also could've done a better job in their communication.

Additionally, people may as well just get used to at LEAST expecting games to be a little broken on day one of release. It's just a reality that's not ever going to roll back to the "old days", no matter how much people bitch about it.
