I'm all for hating on Ajit, but from a cursory look at the prison case, the FCC just never really had the jurisdiction to regulate intrastate calls and repeatedly lost in court on that question. There was already a 50 cent cap on interstate calls under Pai, and this year under Rosenworcel it's been lowered to 14-21 cents[1].

Am I missing something?
