The ISP duopoly/monopoly is worse from a consumer perspective and functionally equivalent from a civil rights perspective. To think otherwise is naive.
In fact, the private sector solution is perhaps even worse from a civil rights perspective.
Consider a prosecutor in Jurisdiction A hell-bent on violating the civil rights of a citizen in Jurisdiction B, and suppose Jurisdiction B is sympathetic to this citizen. This isn't even hypothetical in the USA. Abortion, immigration, civil disobedience, etc. In the corporate duopoly setup, Jurisdiction A can compel the ISP to comply -- either by physically entering the property of the ISP and taking data by force, or by threatening market access. In the muni ISP case, Jurisdiction B says "shove it".
And that's before noting that corporations such as modern ISPs are -- like governments -- also large bureaucracies endowed with incredible power that are de facto impossible to opt out of. Except at least in representative government you have some sort of voice, however small, which isn't dependent on amassing vast sums of cash.
