As someone who used to follow AKB48, traditional idol culture, before the term got picked up and bastardized by westoid redditors and twittards, is entirely premised on the underdog story. It has nothing to do with pretending to be your girlfriend. It was about ordinary girls you could find on the street who were diamonds in the rough, who could be produced into singing and dancing superstars, and the fans who supported them along the way through thick and thin. That's what idol culture is in the AKB and Morning Musume sense, and in multimedia like Love Live and Idolmaster. That's why they are marketed to be normal and approachable, and why innovations like the 'idols you could meet' concept by AKB were such a hit. That approachability did get warped over time into a sense of exclusivity and idols being idols 'for the sake of the fans', but that's beside the point.

Yagoo took inspiration from AKB when starting Hololive. He used to compare Hololive to them, that's where that overused Yagoo's dream meme came from. A Holo should never, ever tell their fans to go improve themselves, because they used to be nothing as well and it was precisely because of their overweight, stinky, sweaty weeb fans and their money that they could become something. To suddenly say that their fans are the problem now that they have become something is unacceptable. You don't have to be a unicorn or even a Teamate to find that disrespectful.
