The dev was a toxic person who had mental health issues. Not the first time they freaked out and claimed they were being targeted for harassment and throwing a hissy fit and leaving while being a toxic turd to so many people along the way
Told people to kill themselves for asking questions and actually got caught making up "evidence of targeted harassment" it was a pretty big issue in the community at the time. He made up death threats. For attention.
At first people were sympathetic until we learned this isn't the first time this dev has done this
