In constrat, in the UK, we unbundled our ADSL monopoly, and forced them to sell access to the cables wholesale. And then let competitors put their own hardware in the local exchanges too.

It still needs more work as everyone seems to have to charge a fixed line fee. There are though plenty of providers with varying prices and qualities. Plus cable (fibre) too.

Competition and capitalism only function if a state heavily regulates the market to be an actual market.
