I disagree, as does Tyson Fury. It's good for the sport as it brings in a whole new audience and some of them will stick around for other pro fights. I think it adds a little spice to the sport. Big fights tend to take ages to get sorted whereas these big-money match-ups get sorted pretty quick and they're often fun to watch in between the big main pro events.
I'm kind of sick of it, though I'll probably admit that its been beneficial to boxing as a whole. I've felt for years now, boxing has been on the decline, and these Youtubers certainly put the spotlight back onto boxing. I used to watch quite a bit of boxing, but these days I only really tune into my favourite fighters, and most of them are in the heavyweight division. UFC played a part in my interest waning, but I've definitely focused on boxing a lot more recently due to this....circus? I don't know if it's fair to say that, the Jake Paul vs Tyrone Woodley fight was actually alright. The Jake Paul fights before that were ridiculous, but I guess the Mayweather vs Logan fight was OK.
My biggest gripe with boxing is the politics involved in matching up fighters. Joshua, and Fury should have already fought, and it's annoying as a fan to be strung along, and then the big fights end up happening when they are no longer in their prime, making it a bit of a farce, due to the fact they wanted to milk the hype behind them as much as possible.
