I think a lot depends on location.
I can get Brighthouse, U-Verse, telco DSL, or satellite internet at my suburban Indiana location.
I use the competitive quotes to batter down the price at renewal time.
Those are all different products. DSL is, btw, open to competition in most areas but few still do it since it is one of the slower alternatives. Satellite involves the cost of launching into space and yet there are still 3 competitors. But your coax cable is still a monopoly.
Oh, and yeah I know some deliver TV, some deliver streaming content etc. I am not arguing that “internet access is a right” but it is something that is evolving with technology and is simply bad public policy imho to let a small handful of people control it. Even if it is regulated and supposedly they can only censor things with no redeeming quality (same standard as print) - they are slowly moving in that direction.
