This really seems a nothing burger (ironically)

Is the guy filming annoying? Yes it can be and that's why bigger ones that do this (thinking BeardMeatsFood) usually try to book private seating where possible.

But the other guy off camera was such an obnoxious ass that it's no wonder people 'sided' with the YouTuber.

It's really low hanging fruit as I currently monitor a Tiktok craze to storm Scientology buildings...
