Not really. He's using satire to make a serious point. This isn't a case of lightly ribbing something he enjoys, but mocking something he does not. When Jello likes something, he will usually include some kind of compliment among the jokes, like Gravity Falls, for example.

It's honestly become quite depressing how the vibe of the RWBY community has collapsed to the point it has. Like, the only positive content I ever see is lewds and, well, that's basically it. Like, even the "fanbase"(ie r/RWBY) seems more interested in shitting on Vic than the show itself. It's just, it feels like watching a dying puppy.
