Local loop unbundling was required under law wrt dial-up and DSL until 2006, when DSL was reclassified from being a Title II to Title I, service, correct?

It was my understanding that Title I service providers, like cable companies, can use the lack of LLU requirements to charge exorbitant rates to competitors who want access to someone else's local loop, which secures the incumbent's effective monopoly in a neighborhood.

Would love to be corrected here if I'm wrong so I don't spread misinformation about this elsewhere.
