It was just various small things that added up over time I guess. Weird moments where it felt like she either didn't appreciate her audience or saw them in a condescending light. I just stopped watching after a while, but I think a big turning point was her being two hours late for a stream and, instead of immediately coming to her own stream, she went to her grifting fucking Gen mate's stream (made to leech views from her currently absent genmate) instead. That and the whole debacle with her saying her viewers were pathetic was bad. Everyone was mad about the jab but I didn't actually care, it was that apology that made it go from a fun jab to "wait does she actually feel that way about her audience?"
Granted, I do think a majority of Takodachi are faggots, but if she's looking down on them and I'm technically part of them as a viewer I'd rather just stop being a viewer. Plus I dunno it feels like she became faker after the first two years.
