I think the main reason why people forgive even quite damning things about Cover is because they actually have no fucking clue what they are doing. It's not penny pinching like Nijisanji, where almost all questionable decisions can be boiled down to "it made more money this way" but genuine "we as fans have no idea why cover did it. and neither did cover". They started idol agency as an after thought and a way to promote their vtuber tech. Doesn't mean fans shouldn't call them out on their bs, but not being malicious can give you a ton of leeway
