Just like SNCF or Deutsche Bahn run services vastly worse than our wonderful privatsed railways you mean? Public owned does not necessarily mean bad, you're an ideaologue.
You're also making an incorrect comparison - no one here is suggesting a return to state monopoly of telecommunications. However properly manged infrastructure can lead to more competiton and better, cheaper services for all. Whether that's done through regulation as with LLU or the government taking full control of the infrastructure doesn't really matter.
