This feels like the typical blizzard cop out answer, similar to what Ion said about the Warlock forums (Sorry, can't remember when so I can't find the link).
The root of the problem isn't "... whiny, ungrateful little shits...", you're just giving them an excuse like just because there are trolls and unhelpful players lambasting the devs with insults, then the small group of players who actually do the testing and construct amazing feedback threads so in-depth it puts blizzards devs to shame apparently don't deserve communication either.
Don't give them an excuse for poor communication, hold them accountable. Ignore the "... whiny, ungrateful little shits..." and pour over the essays of feedback.
