Phone companies are utilities and I don’t think they have the right to censor your phone calls merely because of your political views unlike the good old net-neutrality boys are doing to conservatives on their communication platforms. Could that be what they are upset about?
All on or all off is not the right answer.
If customers have only one or two ISP choices THAT CAN DELIVERED TO THEIR BUILDING THROUGH PHYSICAL MEDIUM then there needs to be ant-monopoly, anti-gouging regulation.
If 3 or more are available to the customers building then free and open market competition will thrive if those companies are not in secret cahoots with each other (which is already illegal).
Also ISP start-up rules and regulations need to be made to be much quicker, simpler, cheaper.
