Well, that's just how a vocally loud part of the gaming community is: hateful, entitled, thinking they can do games better than the devs while they know nothing to begin with, and overall terrible human beings.
Most of the people I know working in the video game industry aren't even trying to communicate with fans. The hate and threats they would get is unfathomable, and yet, they have their hands tied as well, because after all, in a video game company, a lot of things can be political, and a lot of decisions can be made by the people who are superior to you, even though they know nothing, and even though people actually making the game know they're fucking up, but can't do crap about it without losing their jobs.
When there's big money, there's always frustrated people wishing to do things right, and there's always people wishing to make more profit regardless of quality. The joy of making AAA Games, right there: having to internally deal with various types of people, from the best to the worst.
Either way, I feel that Bioware are still trying to communicate, and I'm very thankful for that, because I have no idea how hard it must be, and how much hate they have to face and stomach in order to keep some communication alive. Mustn't be easy, for sure.
They're human most and foremost, but I guess it's easy & convenient for some to forget that simple fact.
