Well, firstly, we should acknowledge that municipal broadband isn't a story of completely unmitigated success - there are cases of tremendous failure as well.

I'm also fairly sure that most Republicans would not mind if municipal broadband were run - and competed on - commercial terms. However, if it's funded by municipal bonds that are backed by general obligation (i.e. all taxpayers subsidize, whether they use the service or not) then that seems obviously a problem to me. Even if they're revenue bonds, they're still implicitly subsidized by tax treatment.
