What are you talking about? You can still buy Japanese MMA PPVs, that does not mean Rizin and the UFC are competitors.
Pride did not make money off of American PPVs, which is why many of their events were not on American PPV. Their PPV sales were like 20,000. They made money off of being on network tv in Japan. They were not even played at normal times live. They only had 1 or 2 events in America,
You are a very bubbled fan, that doesn't actually realize how orgs like Pride and the UFC function - I mean it's pretty apparent by how you think M1 and the UFC should co-promote, and that them not doing so is because Dana White is evil or something.
Pride did not have a TV deal in America, and their PPVs were a minor part of their income. Therefore, they were obviously not competitors with the UFC. Most MMA fans did not have to pick between the two.
Western fans have this obsession that Pride gave a shit about them because they were one of the few people watching their events on the internet. Pride was not concerned about the American market and were only trying to breach in toward the end of their run. This is easily verifiable....
Americans going to Pride to fight doesn't mean that Pride is a competitor with the UFC. They are not the consumer. If someone goes to New Japan instead of WWE or AEW, it doesn't mean that New Japan is competing in the American wrestling market. They went to Pride because Pride paid better, not because it was in the American market (which is irrelevant to fighter pay).
It's actually baffling that you were buying PPVs back then and did not notice that Pride is a Japanese product appealing to Japanese people and that their biggest star was Japanese.
