To me personally what annoyed me was that A. He was toting what he was doing as something beneficial to the members, even though the sole reason he did it was to earn money off of their backs. B. He was a condescending prick to members that spoke out (Weird you know, for someone, supposedly helping them) C. He made it so prevalent that it would even show up when you just searched for a Hololive Member or were recommended his videos afterward or in the sidebar. D. He's just an insufferable cunt.
I like finding about their past as much as the next person, but I'm not going to shout it from the rooftops. When I do post something here, it's always private (if it's a YT video I upload). And if someone messages saying that it might be damaging to the person involved, I remove it.
