I disagree, as someone argued earlier the maxim "no such thing as bad publicity" isn't always true anymore. In the age of social media and cancel culture making a fool of yourself in public can easily lead to being blacklisted and losing contracts. He also seems to be a poor streamer so even if he did get a tiny initial boost it won't last but even that's doubtful as his own community turned on him at least as much as the FFXIV players did.

No such thing as bad publicity was a thing when it was hard to make a lot of noise, it's not hard anymore.

Always the risk with negative publicity - it can backfire.

The question is: how has his viewership changed since he did this? Does he have more followers or less?

If he's got more, then the negative publicity worked for him.
