We had a similar sort of thing here in Aus... our incumbent government-run "Bell" telco (Telecom, now Telstra) was privatised and the market "deregulated".. unfortunately competition was (and still is) not really there, and the biggest competitor of Telstra was also its biggest customer - it had to buy access everywhere.
Fast forward to a few years back and the then opposition came up with the idea of the National Broadband Network - rolling out an all-fibre network to around 93% of the population, with a mix of fixed wireless and satellite servicing the rest. A Government funded business that operated solely as a wholesaler, from which retailers could purchase access to market to the public. It would provide next-gen broadband infrastructure to the general populace, and break the stranglehold of the incumbent telcos on physical infrastructure (for which they were compensated) They won the election and got to building it all.
Sadly, the whole thing was hugely political.. the then opposition leader Tony Abbot (who'd later win an election and become Prime Minister) attacked it at every opportunity he could, calling it a massive waste of money, that there was no need for it, all sorts of things. Once they won power, they'd invested too much political capital in describing how awful it was to just continue on with it, so hunted around to find some alternative model, made up some studies to back them up, and proceeded to shit all over the thing.
So in the end, they wound up going from a simple, homogenous fibre-to-the-home model to a "multi technology mix" fibre-to-the-node, with VDSL connections on the last mile. Some areas already had fibre rolled out (or in the process), so they have fibre connections - technically running at gigabit speeds but only sold at levels of 12, 25, 50 (not a common step) or 100mbit. Other areas on FTTN are still subject to the problems of DSL line length and signal quality issues, so while some people can still get that 100mbit, most are around half that, and with the 50mbit retail option being mysteriously missing from many providers, that either leaves people buying only 25mbit connections and missing the extra bandwidth, or paying extra for a 100mbit plan, much of which they can't use.
In short: It was a great idea, ruined by politics. It's still fundamentally sound, but there are a range of issues messing it around, most of which can be traced back to that political meddling.
