Those controversies are over-analyzed. People tend to forget that these two guys are, like all of us, human and don't have some sort of fancy PR machine to soften the blowback. Krahulik suffers from chronic anxiety and so when the threats started piling up, he responded in kind the way an animal gets backed into a corner. There's no denying he fucked up, but curiously his critics seem to gloss over his attempts to apologize.
I've been at PAX. These guys are approachable, they're kind and funny and do not carry an air of superiority. I know their failings as well as I know my own.
