He was highly inappropriate when he was CEO, once having a public flamewar with a disgruntled ex-employee. I'm not surprised by his behavior but I question his motives. Looking at his comment history he seems well aware that he is blacklisting himself from ever holding an executive title again. Maybe when you have nothing left to lose you just start seeking attention?

I'd assume he's a little cheesed off with the reddit board, since they essentially scapegoated her (I'd assume a friend) for their own decisions.

He's posting with admin flair. So reddit is still allowing him to do so? Maybe this is just a PR stunt?

He'd be justified in having a grudge, as a former CEO. But I think it's more that he has no f---- to give and is 100% willing to speak his mind on the topic.

Not a trait I'd want to see in all the CEOs out there, but seeing it in one former founder is... Refreshing. ;)
