Human operators were not required of The Bell Telephone Company by law. Bell switched to mechanical switching stations as soon as doing so was economically advantageous.
(Reconsider my post. I'm arguing for no regulation.)

This is because the telephone system was regulated with wiretapping laws, among others.

It all comes down to whether you view social media as a communications platform or a publishing platform.
The strict regulations governing the telephone system (see above) would adequately cover both with deliciously-antique turns of phrase like "wiretap" and "pen register".
I'd say that at minimum social networks need to be required to show how their algorithm works and allow users control over their data. They must be able to know why a content was served to them. Nowadays social networks are so pervasive in society, affecting it and molding it to unknown interests, that this is the bare minimum for a free society.
Ideally, users should be able to modify the algorithm, so they can get just what they want, while simultaneously maximizing free speech. If something isn't illegal, it shouldn't be hidden or removed.

I think this is the real issue. We should free ourselves from "social networks" such as Tiktok, Facebook, Instagram and others. Even with direct messages truly E2EE, they create countless other privacy problems. They enable surveillance of people at scale and should be completely shunned for that reason alone.
Posts made are like the letters page in my view, but even if you don't believe that should be controlled, when it comes to the adverts these publish surely it has to be the latter.
Personally I argue they are more like a newspaper as they are providing a platform. Your ISP is more like a phone company or postal service as they just transport packets from one person to another.
Cloudflare and similar are more arguable, but to my mind if you host a computer you are responsible for the contents stored on that computer.
Clear, simple, direct: Whatever was required of The Bell Telephone Company and nothing more.
