Ok, this is a really weird and creepy phenomenon at this point.
He clearly absorbs his attitude and viewpoints from other people in real time. Normally it's not this pronounced though. Unironically liking any Vtuber? Says the guy who was a Pippa fan before she rejected him, obsesses over Vtube all day, and desperately wants to be a Vtuber?
I think liking Vtubers only became cringe when he was reading this thread earlier and saw people telling the fat filipino that being a sexless Vtube obsessive was stupid, so now he has to say the same thing he saw other people saying.
He doesn't even have a personality, whatever he's reading or jerking off to at any given time is all that exists in his empty, empty head. Harrowing stuff.
Edit: I didn't see the date on the first tweet, that was yesterday. Still, it's clear the only reason he's saying liking Vtubers is gay is because he saw other people saying it.
