Absolutely. There's huge problems with gaming community and how people treat devs, media, streamers and each other. The guy at the Q&A isn't the worst example of it. But he didn't come out of this looking good either. There's plenty of ways to voice disappointment, without such snark directly towards other people. Looking developer straight to their eyes after they've just introduced a new game and being a dick about it because it's not to their personal interest, isn't something we should be doing. I feel people would understand what was rude here if the game was something else, like let's say Druckmann revealing Lost Legacy. But since people share the disappointment with the guy at the Q&A, they celebrate him instead.
None of the questions asked were even remotely as bad as you are trying to make them out to be.
