What's your point? If they couldn't manage to secure the resources necessary, they shouldn't have agreed to livestream it. As a customer, I don't care AT ALL if it's difficult.
As a customer you're right that you don't care. As a company you care for the cost of the product you sell.
Companies doesn't care about "the customer" per se, they care about their profit margin and "free market" competition pushes them to lower the price and keep the service level good.
Exclusive rights to stream the fight? Well... it better be working, but we won't overprovision and pay over the expected return.
Buying the exclusive rights for 20Mil and puting 30Mil to stream it wouldn't be a very smart choice. Fuckups happen and this might be a mistake that cost them in lost reputation more than they expected to win.
