Cable ISPs were only moved from Title II (common carriers) to Title I in 2002, and dial-up and DSL in 2005.

And yes there were problems, here's a list of related issues and breaches: https://np.reddit.com/r/KeepOurNetFree/comments/7ej1nd/fcc_u...

Not to mention the move absolutely destroyed DSL competition (as its opponents had predicted) as it ended line-sharing requirements.

Furthermore, the FCC had Net Neutrality rules in place until 2014, when the courts decided it didn't have the power to enforce these under Title I.
