I mean I didn't think it was really legitimate grounds. This is just from memory, but I think the issue was that he called out Billy Mitchell for cheating being the foundation of basically his whole career, and then Billy sued him for some minor tangential bullshit mostly just totally unrelated to that. I think you are correct, Jobst accused Billy of laughing and being cheerful about some other streamer killing himself (which he definitely did) but also made some kind of minor factual error while talking about it, and Billy convinced a judge that that was worth multiple hundreds of thousands of dollars worth of damages. That was my understanding of it.

Edit: Mostly I think it's weird to include him in this list because even by the most anti-Jobst reading all he did was slander Billy Mitchell. That seems kind of out of place on a list which currently includes people guilty of pedophilia (Miranda), mass plagiarism (Illuminaughti), and some sort of unholy systematic turbo-pedophilia which is hard to even summarize (Onision).

Also, I'm a little disturbed that I know the details of all of this weird pop-culture drama bullshit. Maybe the real streamer slop was inside us all the time.

Did they? I didn't. IDK, I just looked at view counts on his recent videos and they've definitely gone down pretty substantially (which sure isn't ideal) but it's not a full cratering and then a year of silence like Illuminaughti.
