Why/How is this a free to web fight

This is just a guess but it might be due to amount of followers each fighter has?

Because the guys fighting have barely any followers.

Like I see that. And in this fight I can tell its the class. But unification bout. Idk. I might restart and run some testing on promotion

If you make that a main event, and put on a full card (6 or more fights) then doesn’t that change?

Josh Taylor vs Ramirez Unification fight in real life couldn’t even get a UK broadcaster, doesn’t matter about the magnitude of the fight skill wise and legacy wise, if no one cares for the fighters then no one’s buying and it looks like the promotions both knew that here hence they made it free
