Lack of choice and collusion by the major telecoms.

If you're going to implicate every major US telecom company in a massive conspiracy to commit a crime, you should probably have a source.

It's possible to infer collusion from indirect evidence, especially extraordinary pricing. See American Tobacco Co. v. United States, 328 US 781 (1946). It's not common, but it's not crazy either.
