Now, given that major social network advertise pretty much everywhere, this might not be an entirely fair analogy. Some parking lots have ads for them posted in every other parking lot. But it's a point worth making that access is relatively egalitarian on the internet.
If a tree falls on the forest, and no one is there to hear it, did it even make a noise?
Also relevant is this very interesting research experiment conducted ~5 years ago on social media manipulation, in which they dubbed the term "Censorship 2.0"

You can't decide Facebook is subject to a different set of laws or has fewer rights simply because people have arbitrarily decided to communicate on its platform more than another platform. Every private entity should be afforded the same rights to regulate their private property or services unless there is legislation specifically saying otherwise.
If you or any other person do not like the way Facebook is regulating usage of their platform, you are free to go start up your own social media platform with a different ToS (and many people do).

Oh but we can, that's what democracy and law makers are for, and if you've been keeping up with the news at all for the past few years, you'll know that's where we are increasingly likely to be heading.
