> Even if it’s hard to stop using e.g. Facebook, it’s easy to access 1000000 other sites too, and publish your own.

There aren't 1000000 major social media sites. Sites with fifty users in total are irrelevant and can't be used for the same purpose, and for the same reason most people can't feasibly start their own.

> That’s not the case with ISPs - for the most part you can have only one.

This is also not true. You can generally choose between the "cable company" and the "phone company" in addition to satellite providers like Starlink and various cellular networks. You have about as much choice in ISPs as you have in social media sites, and in both cases it's not much.
