Thank you for using my clips in the video, and here is a little extra observations I'd like to provide.
While the EN's branches void of collabs is the most apparent, it's also been noticeable that even in the JP branches, external collabs(Nijisanji or otherwise) with Holo also had gone way down after the Taiwan incident.
While some pairs certainly are still good friends with each other on stream (Tokomachi, Haachama and Hoshikawa, Okayu and Shiina), some who used to be very close on stream also suddenly ceased despite some having promised more collabs(MaiSuba, Matsuri and Yashiro, Korone and Flare with Debi, Marine and Hayase). Like on the EN side, some can still drop tidbits that the talents themselves are on good term (Marine cameo'd as Pikachu voice on Hayase's 3D reveal).
But otherwise, Hololive's interaction with the outside had just gone down significantly, since Inuyama Tamaki also had fans asking question why all the Hololive collabs suddenly disappeared. The answer Tamaki gave was that Hololive members are very busy, and yes looking at their schedules this is true to an extent, but this was seasonal as they also showed that "off-season" when there aren't any upcoming concerts, they have significantly much more free time, so it is dubious to think that this "busy" reason would be year-round. Not to mention the fact that some members can freely just drop a 12-hour guerilla stream out of nowhere seems to indicate schedules aren't really a concern.
It is extra noticeable since to this day, Hololive gen 5 and 6 barely had any collabs with anyone outside Holopro, while at the same time Holostars external collabs continue happen on a weekly basis. Though at least this looks to be improving with Tamaki's recent collabs with Lui, Laplus, then one with Aqua after over a year of silence.
But like EN, the blame isn't entirely on Hololive. On Mayuzumi Kai's final totsumachi before graduation, Matsuri came on as a guest and Mayuzumi explicitly stated that the 2 companies relationship hasn't been what it used to be. This is while Mayuzumi himself had stated that he left Nijisanji because of their changes in policies. I would have clipped this moment but unfortunately Mayuzumi requested no clips be made from that particular stream.
