If you're suggesting they really do have 1000x the costs of companies whose core business is internet, and yet they refuse to contract with those companies to deliver the service (they can still get 990x profit while still leaving 10x for the other company) in a rational market that would be a business-ending level of incompetence.

It's no different than if I'm selling apples for $1000 each. Even if I can find one or two customers willing to pay that, wouldn't I have to be pretty stupid to spend $900 growing each apple incompetently when I could just spend $2 at the grocery store to fulfil those orders?
