This is really nothing new. Devs have been talking like this for years. The major reason for this is that anything they say, and I do mean ANYTHING, becomes gospel. Gamers take anything said in a concrete manner to be absolute. When things don't pan out as planned, devs get crucified for going against their "word."
If they say nothing, people say they don't care. If they talk, people say that they are pandering and overly generic.
Devs are in a lose-lose situation in terms of community communication and interaction. This isn't a defense of BW specifically. Take a look at the way in which WoW's blues get treated as well.
