Why is this even a take lolw. Dude never intended to "insert himself" into any corpos, actually even the opposite. One of the rare wholesome streamers who just wants to play games and wants none of the clout chasing/drama shit/corpo from the streaming scene. He plays games when he isn't streaming. He moved away from LA the moment he can afford to. There was a point where his best friend Valkyrae tried to sign literally all of her friends into 100 Thieves (and she managed to score like 5 of them) but he just donowalled her.
If anything, he deliberately never called Gura by name on stream. Most mentions of Gura were his friends giving him shit about hiding his chumbud status and trolling him. And he's a certified stream watcher too not just clips.
As for holo vtuber, he did interact with Altare (just like the rest of the OTV friend circle). He also followed ollie on twitter but never collabed? Anyway that was years ago, he probs stopped watching vtubers with gura's disappearing act. He is friend with Shoto but so are many male streamers. I dont think the guy "inserted himself into indies", he really just treat doki as a friend for this occassion.
