So Kero declares he won because he's going to keep making content privately, even though most furmeets and conventions are going to keep him banned. I don't know how it's a win when most furries want nothing to do with you, but okay.
So hypothetically speaking, if Kero were to go back to making content behind a locked paywall (eg patreon only videos), who would even watch them, let alone care?
If you'll pardon the weird example, it's like how that Peacock streaming service exists and their only real selling point is they're the only place you can legally watch The Office, so the only people who care about Peacock are people who were already fans of that show. So in other words, the only people who will give a shit about Kero's future videos are a small chunk of furries who were already fans of his, and given how incredibly awful a lot of his white knights are, it seems like a fitting fate for Kero.
Either way, if this means Kero is going to fuck off to a tiny corner of the internet and nobody has to acknowledge him in any way, I'd consider that a win.
