Selen's team actually won one of the matches today. Granted it wasn't a full 20-man lobby due to it being Patch Day, which is notorious for breaking the game, but still required lots of professional decision-making in order to outmanoeuvre teams like Restya, RPR, Tempplex, and Virtual Gorilla. They're quite a deceptively decent team.
There are actually a decent amount, and more importantly there are a decent amount of people who only clip one Niji. Just today I found someone whose been chipping out Hayama Marin clips for over half a year now. They just don't get a lot of views and the algorithm certainly doesn't favour them. Niji clippers are the true rabbit hole.
Yeah your mileage is going to vary on that kind of content. I don't think I could handle 70 minutes of cute noises and a very palpable language barrier, so imagine my shock that it was actually pushed by Cover and there's like 5 more of them just this week.
I can only surmise that someone in the Marketing department has seen the amount of traction, fanart, and fervour HoloBirds gets and has decided that they want another themed group with more marketable members.
And while I personally don't care much about 'artificial' groups — nor do I care much about the opinions of a 4ch board that has a hobby of spending hours placing 'bets' on livestream viewer count predictions — I can see why some people may feel it's a step too far in a community that has, up until now, always had a more symbiotic relationship with the streamers regarding how these wacky group/ship names come about in the first place.
Edit: I can only speak on what I've seen from other sites, but I find it ironic if UMISEA is getting heavily pushed by management and all anyone was focused on was A-chan carrying the stream. Give her her own fucking channel already. Christ.
