So - the principle that the Government had previously been and is now operating on (except during the Obama administration) is that intrastate calls and commerce are properly regulated by the State. Courts have repeatedly ruled this is the case. A normal person would think this is unobjectionable.
So, to say that Pai "caused" the present situation by returning to the Constitutional status quo ante is palpable nonsense. Further, the article states that Pai is "begging" States to take care of the problem, and presents no evidence to support the claim.
The only reason this article was greenlit on slashdot was an arbitrary shot against a Trump administration official that people don't like because of his stance on net neutrality. Remember that whole thing, the blackouts? If, we were told, NN wasn't imposed, an apocalypse was going to instantly destroy the internet as we know it? Curiously, as always, it turns out, that's not where the threats to freedom of expression came from.
There's another twist to this: why, exactly, are the regulations on the utilities, instead of on the prisons? Prisons are highly regulated already, are already under lots of constraints for what they can and cannot do, and States and the Fed executives are perfectly capable of replacing their service providers, and private prisons are already subject to contracts with the State - all problems can be fixed in a year with a flick of a pen of some mid-level executive. A perfectly coherent way of handling this would be to put the service contracts to a public competitive process like most things that are procured by the State, and be done with it.
