Sven is unironically his own worst enemy. Way way back in the day, when the Sven "no so much" meme was born, people were talking about how much of a douche he was acting and instead of thinking "Hey I don't mean to be a douche, maybe I should try being a bit kinder" he doubled down intentionally on being rude and alienating his audience. In fact, many of the forum shut downs occurred because he didn't like their criticisms and couldn't handle it.
I can handle someone coming across as bad, despite their intentions, reflecting on things and openly stating you'll try to be a bit more understanding of others, but there seems to be the American phenomena of "Fuck yeah I'm an asshole, get used to it!" that just doesn't work when you're running a small business.
There's a difference between being a bad dude that people want to be friends with and intentionally shutting down a web forum because you're having a bad day. Napoleon complexes aren't cool they're petty, and that's what Jesse is, a petty little man.
