Your incumbent killed the local ISP's project. Fibre customers generally won't change ISPs in the first 2-3 years of having service, so being undercut by the incumbent makes it worthless to continue with the cost of construction when you'll only get a handful of customers. I know because the incumbent has done exactly the same thing to me. A project that planned on having 140 customers can't be supported by 5.

They're actually still rolling out, just slowly. Of course, this might well have caused the slowdown.
