It's a piss take. It's the same with the UFC aswell now. BT sport are making certain events PPV because they're greedy bastards.
I can't think of many other countries that have broadcasters who would put on PPV events at 3/4/5 in the morning with a non UK fighter in the event.
I get it with fights like Mayweather-Mcgregor or Mayweather-Pacquaio but otherwise it's just a joke.
