I'd argue that Facebook itself is protected 1A speech (as are the recommendations of the YouTube algorithm). It's not a consumer product, and it's not a defective one. Parents have parental controls, and they should educate themselves on how to effectively use them.

I suppose that the broader concern is over precisely what duties a company has to its customers. They obviously have the duty to be truthful when making offers, but every customer relationship will have an adversarial component where each party benefits at the other's expense (or at the expense of third parties). In cases like a bar serving alcohol to customers, there's usually some responsibility to prevent patrons from getting extremely intoxicated and getting in a car. But that case involves a clear signal that someone is dangerous. Facebook doesn't know if someone's grades are suffering or if they're having mental health issues. It doesn't know if it should tell the user to "touch grass".
