Yea. I may not like the idea of it but from a strictly constitutional view it seems correct. ISP's are private entities after all. We already have major social media platforms, hosting providers, domain registrars, payment processors, credit card companies, even DDoS protection companies all "exercising editorial control" of content, so why not ISP's?
The argument of "ISP's choice is very limited in many areas, so it's different" seems rather weak to me. You can just use a cell carrier, or satellite, or even dial-up. If that sounds like "you can just start your own social media platform, your own website, your own payment processor, your own registrar, or just be accessible through an IP address, or tor etc." it should. All those options suck. Yet the people who are most militant about Net Neutrality are usually totally okay with every other private entity doing whatever they want (as long as it ends up aligning with their ideology).
I'm not here to suggest any solution to all this, just to say I don't think there's anything untoward about a judge ruling in line with the first amendment of the Constitution. Ideally this whole mess will lead us towards more competition and decentralization on the Internet, but given the way it has developed in the past 20 years, I'm not very hopeful.
