Not saying that I agree with what was said, but I'm pretty sure in one of his other letters he said he wouldn't try and be as personal. Don't know which one it is but I'm sure you remember exactly what I'm talking about. Everytime I read something like this after he said it, I think back to that time he said that. Which is the total opposite of what he's doing now lol.
And what does blizzard have to do with this subject anyways?
