The Factorio dev. I’ve heard he’s a shit person but not dove deeper into it.

Edit; did some looking and yeah, he’s a shitbag. He claimed that Statutory Rape was a SJW term, and that teachers should be able to seduce their students as long as they weren’t violent.

Then he used a dev blog to link to a racist misogynistic jackass, and when called out on it (The guy just wanted a disclaimer on the link) Korvex went on a rant about cancel culture and then tried to defend the misogynistic views, claiming that “maybe there’s a reason why there are so few women coders”
