Yes but again this isn't really about freedom of speech, just as it isn't really about due process. The State of Mississippi made a law that says children cannot access certain platforms online. That's what happened here (and incidently limiting children's access to things was far more common in the time of the founders). Many people are happy with the law, many people are not. Those unhappy can talk about it all they like and make an effort to vote in new lawmakers who will repeal it. They might succeed, they might fail. Depends on public opinion. Pretty sure that's how the founders would see this one, as a simple case of split public opinion and the legislative process running itself through, nothing to do with some kind of due process or freedom of speech emergency.
