The distinction is between perfectly legal speech, and specific acts fraud or things that are direct, actionable, and credible threats to physical safety (e.g., bomb threats). This isn't a complicated blah blah, where we need a technocratic meta-god to put his thumb on the scales. The existing legal pre-computer legal frameworks cover these cases.

They might get cut off for robocalling, but (if the telephone company is obeying the law) in a content-neutral way.
