I don't think the phone company should be shut down because others can use it in a way that's considered devious. I don't think the phone company should play "morality police" either. I simply expect the phone company to simply provide the service I paid for.
This type of thinking strikes as the kind that would damn Gutenberg for inventing the movable-type printing press because print has been used to disseminate propaganda and debauchery to billions of people several centuries later.
In my parent post I was giving an example of an absurd imaginary situation with phone companies attempting to amplify sex trafficking by directly deciding who will participate in the conversation for the purpose of increasing engagement.
They also got amplified whenever long distance calls got cheaper (as the overall volume of conversations increased).
