I dunno, man. It's not as if my vote on the matter is going to sway the position of the thread one way or another, but it just seems like normal Nick behavior to me. His reaction in the video linked is exactly what I would expect to see from him if KF labeled him a lolcow back in 2019. It looks a little worse as it appears he was in a livestream and people kept asking him about it so he went on longer than he otherwise would have needed to, but there's no seething or chimping out. I don't know what he's referring to in the video as 'pointing and laughing', though.
It seems like he just got moved here because he got too degenerate and people were looking for excuses to finally get to say "I knew it! I knew he'd become a lolcow! I told you so!"
