Frank Warren fired shots at promotional rival Eddie Hearn at the Tyson Fury weigh-in on Friday in Manchester.
The legendary promoter pulled no punches when quizzed on Hearn's pay-per-view offerings and Matchroom Sport's partnership with Dazn - a live streaming service that could spell the end for box office bouts.
"I don't know how they've got the cheek to do it," said Warren, after the news broke that New Zealand's Joseph Parker will meet Brixton's Dillian Whyte on Sky Box Office.
Unified heavyweight champion Anthony Joshua wiped out Whyte with a monster uppercut in 2015 and outpointed a gun-shy Parker back in March. Joshua's former foes now headline what's expected to be a stacked card on July 28 at London's O2 arena.
An unimpressed Warren said: "I wouldn't pay 99p to watch it. It's not a pay-per-view fight, it's a good fight but it's not pay-per-view. I wouldn't pay to watch it."
"I bet everyone that's got to pay £19.99 to see Parker and Dillian Whyte will be looking forward to the end of pay-per-view," he continued.
Warren's remark was in response to Hearn's claim that pay-per-view match-ups could become a thing of the past.
In March, the Matchroom Boxing head honcho announced a 'billion dollar' deal with Perform Group's Dazn streaming platform. The subscription service launches in the States this summer after success in Canada, Germany, and Japan, and has been labelled 'the Netflix of sport.'
At the DAZN-Matchroom press conference in New York, Hearn said: "There will be no pay-per-view on this channel, this is one of the models behind this. The aim here is 12 big fight nights and four absolute monsters."
But Warren, who pioneered pay-per-view fights in the UK during the 1990's, isn't convinced by new the way to consume boxing.
The 66-year-old said: I don't know what it is all about, we'll have to see what happens in due course. But you can't one minute slag off pay-per-view and the next minute you're exploiting it to the limit by putting on fights like that [Whyte v Parker].
"How on earth can you expect fans to put up money for that, they're not going to, it's ridiculous," he concluded.
When The Sportsman caught up with Frank on Friday, he also waded in on Matchroom's controversial partnership with secondary ticket retailer Stub Hub.
