What crawled up your ass and died? seriously! I have seen him go out of his way to help people. Even me a little while back so excuse me if I take offence to your comments.
Have you ever seen him go out his way to insult them, though? Or, indeed, proclaiming himself to be an 'alpha leader' (so he doesn't have to listen to people), and then insulting a dutch forumite for a slight linguistic misunderstanding. Or claiming poor review scores are the reviewers fault, not his.
And...well, you could go on for pages about this. But he displays the most unprofessional attitude towards prospective customers I've ever seen in a developer. Which is why I don't like him.... I mean, most people would try to be courteous and polite, even if they feel they are being insulted, but he doesn't - just goes to being the lowest common denominator in a one.
And if there are 2 traits which are good at pissing me off, it's unjustified arrogance and unnecessary rudeness.
