But why didn't Supreme Court find the first ammendment arguments compelling? As per first ammendment it is legal and protected to print/distribute/disseminate even enemy propaganda in the USA. Even at the height of cold war for example Soviet Publications were legal to publish, print and distribute in the USA. What changed now? Even a judge, Sotomayer said during this case that yes, the Government can say to someone…
You can say whatever you want on a telephone call.
BUT:
The telephone network is regulated. Your cell phone must comply with FCC regulations. You personally may have a restraining order that prohibits you from calling certain people.
IE, if a phone is found to violate FCC rules, pulling it from the market has little to do with the first amendment.
