I see you guys trying to spin this, but the fact is you can't. It doesn't look good, plain and simple. Nobody cares how he enjoys playing the game, but when he's representing Bethesda to the media and then tells them how much their dialog svcks, then what is everyone else going to think? It most certainly is unprofessional.
Maybe you don't care, and that's fine, be apathetic about it. But don't pretend this isn't going affect anyone's view on the matter or cement the opinions they already have. It certainly has for me. Bethesda simply is not good writing. They can improve, but they haven't made a game yet where the writing is spectacular, or even average for that matter. GTA has better writing than a Bethesda game. Their plots tend to be as deep as a mission in Call of Duty.
And by the way, with his particular job, it's important to keep your opinions out of the limelight. I mean, I'm all for him playing the game the way he wants to. But defending it as ok is the same as defending someone who changes his facebook pic to a butt-naked dude wearing a santa clause hat and wondering why the human resources rep threw his resume out lol.
