The telcos don't owe users anything more than is specified in the contract. The telcos are a company; there is no moral reason to force the ISPs to do anything more than they contracted to do.
Instead of having everyone continue to be pissed off at the shitty monopolistic telcos, and having the telcos continue to be pissed off because we keep demanding that the government squash the telcos' rights to provide a shitty service, let's work to change the situation so that telcos don't get exclusive rights to public resources like land and spectrum.
Telcos and cablecos that own the lines in the ground are not an ordinary company; they often have a monopoly granted by the city that prevents others from running a parallel physical deployment, which would be wasteful anyway. Further, the last mile physical deployments are often subsidized by taxes.
As you say in your second paragraph, removing the exclusive rights held by telcos and cablecos would be one option, but since running parallel cables is physically wasteful, I'd prefer common ownership or regulation of the last mile to save companies and customers the expense of running a parallel cable, while ensuring competition beyond the last mile.
