To some extent, I agree. But while you'll never craft a perfect response and some people will always call your response, "Not enough," or, "Disengenous," there are better and worse ways to do it. Dan Harmon sexually harassed a coworker, created a toxic work environment, and harmed one of his writer's careers. When that started to come out, he talked to her first, then he laid all the cards on the table, took full responsibility, and talked about how he's trying, not always succeeding, but trying to improve and not do the same things again. It's impossible to ever say that a simple apology is enough, but even the person he hurt said that his was the kind of apology that people should strive for. It was brutal, honest, and it didn't shy away from anything. He admitted fault and talked about the very real and non-idealized path forward.
LMG's response... Was horrible. Even if the apology was only for the bad data stuff, it felt like one of his joke videos like the April Fool's Day slave farm video, in tone. Sponsor segues, jokes, merch promotions, things like that. I admit that maybe a little humor could be justified because some people make jokes when they're stressed out, I do that! My mom was damn near on her deathbed a few years back, barely made it out of that alive, and between the sobs, I cracked jokes because that's how I handle things, so I fucking get that! But that was a scripted video that was supposed to be their apology to the fans, and it felt like an insult. They didn't feel like they were taking the accusations seriously, it didn't feel like they were taking responsibility for the problems, and it didn't feel like they were serious about making changes going forward. It felt like a hollow, "This will help us ride out the storm," response.
So, I agree with you that even if they'd done the best apology video they possibly could have, people would have still criticized them for it. You're right. There's no way around that. But it doesn't change that that's not what they did. They put out that apology video instead. And that was just an insult.
