I think it's no secret that Holomems tend to only collab with other Holomems, and are more or less quarantined from every other Vtuber company. Nijifags often portray this as a negative, saying that Hololive lacks "variety" and "chemistry".

But ever since NijiENs started mingling with Vshojos and Twitch indies, they've acted a lot more like Twitch streamers, and have gained significantly more drama as a result.

Meanwhile, you go to a Hololive stream, and it's like night and day. They swear way less, they don't talk about dicks and cum all the time, and they don't get into drama nearly as often because they're raised in a culture that discourages drama.

TL;DR: More out-of-company collabs does not mean more better
