If they were neutral platforms just showing you what you‘ve specifically searched or followed then that would make them more of a common carrier. But the recommendations are an issue.
OK, that's fine, we'll treat them like common carriers and regulate them.
Common carrier is a great model for this. AT&T isn't responsible for the content of phone calls, and they also don't exert any editorial control over them. Many popular platforms are kind of trying to be free to do whatever, but also exert editorial control, which seems untenable.

AT&T is a common carrier for mobile and voice services so I'm not sure why you are raising them as a counter example. While they are not responsible for the content that is sent on their network, they do work with law enforcement and the intelligence community to ensure that specific crimes which occur only over telecommunications (i.e. threatening someone over the phone) can be investigated and proscecuted.
> and they also don't exert any editorial control over them.
Also, this is a requirement of being a common carrier. They have to send everything from A to B regardless of (lawful) content. Facebook, Twitter, et al, seemingly want to create an environment in which they can self-editorialise but are not held up to even the basic standards of a common carrier.
There is a whole series of FTC v AT&T lawsuits which outline this argument and the extent to which they are subject to FTC regulation, if you're interested.
A case could be made that, yes, they are if the leaflets are obviously threatening.
> Are phone companies responsible for the content of the conversations that take place over their lines?
No, but they are responsible for a) not self-editorialising them (which Twitter, Facebook, etc are) and b) are responsible for assisting investigations where such crimes take place. Facebook cannot even tell who is paying for their advertisements. This wouldn't fly for a telecoms company.
So Pelosi opposes this and thinks "internet companies" should be held accountable and monitor every single communication or media file posted on a website/platform. So it's just private censorship mandated by the government. Pretty unoriginal work around to suppressing free speech.
