I can't find it viscerally in me to take moral issue with the guy releasing the code. I understand it belongs to Blizzard, but I just don't feel sorry for them. Not defending that, just stating a fact about the absence of an emotion in me.

That said: if you believe the guy would've been right to distribute the code, it follows that you believe the right thing for Blizzard to do is to release the code themselves. Instead of arguing morality here, one might spend one's energy articulating that argument to Blizzard instead.
