This is just for promotion.
It is ironic that Oscar holds so much resentment towards Canelo. When Oscar was a fighter, he had a falling out with his own promoter, Bob Arum, and had to take legal action to get out of his contract.
When Richard Shaefer was running Golden Boy, Oscar also didn’t see a problem with fighters abandoning their promoters to pursue other opportunities. He was one of the biggest beneficiaries of the Mayweather vs. Top Rank feud, which resulted in Golden Boy promoting most of Mayweather’s fights at the end of his career. It wasn’t until Haymon took much of his stable and later when Canelo left, that Oscar felt what it was like to be betrayed by his own fighters.
Lest you forget, what they did to one of their supposedly partners, because as far as I remember, they have also Shane Mosley together with Bernard Hopkins as business partner of Oscar Dela Hoya in the early stage of Golden Boy.
But they ditch Shane, after his contract with Golden Boy and then just gave him 5% stake in the company.
So in any case, Oscar is also a snake and it's just maybe payback for him when Canelo left him and sure does if Ryan Garcia will also do that as they have already a history of falling out and even Ryan has filed lawsuits against Golden Boy.
