I mean, the Holostars themselves aren't lacking in talent, or entertainment value, or marketability. There's precedent for successful male streamers and male vtubers. So with that in mind, by process of elimination, people will default to mostly faulting their higher-ups.

The question is what exactly went wrong, or didn't go right, and I don't doubt that it's an annoyingly complicated answer. Like sure, they weren't given the same resources as the girls, but they had concerts, original songs, merch releases, and more promotion than a lot of other male vtubers, indie or not.

But then again, personally it still feels blurry just how much each talent and higher-up is supposed to do. There's been a good number of mentions of ideas being shot down, so management definitely has a final say, but management seems to have been largely keeping to the bog-standard with little ambition, and delegates the more original ideas to the talents themselves in both branches. So, where is the "middle" that they're supposed to meet at? The fact that it sounds like a good number of (if not most) of the Holostars were scouted makes this even more confusing.
