Repeal took effect today.
As of late May, 29 state legislatures had introduced bills meant to ensure net neutrality, according to the National Conference of State Legislatures.
Still, several of these measures have failed, some are still pending, and not every state has taken such actions.
It certainly isn't. Net Neutrality isn't a Federal regulation, it's a broad principle. It can be voluntarily upheld by ISPs, as it was for decades, or it can be enforce at the state level.
With actual competitive markets for retail Internet access, specific regulations like this wouldn't be necessary, as customers could choose to leave non-neutral providers.
