You're talking about an entrenched system that was inherited from physical landline service, vs a completely new federated system built on entirely different principles.

If I said "hey you should get a cellphone. I'm on Verizon." And you went to Verizon to be like "hey my buddy said I should sign up" and they're like "sorry, not taking any more customers, you should go find a list of other carriers to try, there's several dozen of them" that would be friction.
