I think you expect that government works "fast" and that is usually not the case unless it's a dire emergency. The wheels of government are just slow. Net Neutrality is important to codify/enact and that's what they've done, I'm certainly not going to complain about it. There are a lot of other nits I have to pick with Biden's policies but this isn't one of them, better late than never like it was going to be under a second Trump term, and could be again.
