Aviel did run Idol Corp into the ground to sell it off to Brave Group for the highest possible price and fleeced the consumers by selling merch that he never intended to deliver that Brave Group had to manufacture once they acquired the group. If you're a fan of any of the girls at Idol Corp, or just want a functional vtubing industry that treats talents and fans well I can understand hating Aviel.
For context, this is a random schizo who used to clip for Matara before being canned for being too schizo about Nijisanji's efforts for the talents a while back. He's bad luck, he can stay an Idol Corp fan, thanks.
