Comcast/Verizon/Time Warner Internet Monopolies?

Well, in 1979, my Anderson-Jacobsen 110 baud modem was also functionally the same…

I’ve had two different DSL providers, Comcast HSI and now FiOS. DSL just cannot compete - so the only real competition is in the FiOS service areas, which are few and far between.

Back to the OP, HSI is local monopoly in most areas.

No, it’s not. A modem is a low speed Internet connection. It is not the same as an “always on” high speed Internet connection.
