This is a common talking point against the FCC retaining Title II classification. While I don't disagree in principle, until Congress acts, Net Neutrality is only achievable in the US via Title II enforcement by the FCC. The FCC reclassifying ISPs as Title I without a corresponding push to have an alternative Net Neutrality plan in place was irresponsible, unethical, and against the will of the constituents of all parties. Ire at Congress for not acting is completely reasonable, but acting as if what the FCC did was in any way acceptable is not.
It's Congress's job to be responsive to the will of the constituents, not the FCC. Congress has done a masterful job over the past several decades of outsourcing all the hard and potentially unpopular decisions to a regulatory body and then beating them up for their decisions.
