I believe you're confusing "entitlement" with "holding Blizzard accountable." They've already admitted fault, but simply admitting fault isn't enough. While it's fair to say the more rational among us realize they're working on more than a simple 4000 honor reimbursement, it's understandable and actually reasonable that many more want swift satisfaction, though whether that's technically possible at this point remains to be seen.
In the grand scheme of things, maybe you personally won't miss the people who are threatening to or already have quit over this, but I doubt Blizzard finds this to be an acceptable loss. There's no reputable business that could commit such an oversight and expect to get away with it. I'm fairly sure that not only would Blizzard not want us to merely look the other way, but that we expect it to do the right thing in return.
Perhaps the reality is that it's a bit too much to ask people to step back and rationally weigh the decision to continue playing or quit. But as the trolls love to say, it's just a game, and mistakes like these cause people to find other ways to occupy their time.
No one is going to quit this game over something so trivial and if they have, they were already considering it beforehand. Good riddance I say, the less whining on the forums the better.
I should thank you though:

I haven't laughed that hard in a while.
I'm not trolling, I promise you. Blizzard Entertainment is a video game company, they're only accountable for making sure you can log-in to servers and play the game. Nothing else. The character you're playing on, isn't even your property, it belongs to Blizzard. Get off your high horse and realize this is a video game.
Why not complain about something that matters like world hunger or equality in the real world. It's much more fulfilling, I promise.
