I don't disagree that there is only a probability, but I think you are ignoring the very likely possibility that this is part of a multi-facet pressure campaign on social media companies by this president, his attorney general, and the Congress critters who are sponsoring this legislation. Using vague wording in legislation is a "bad code smell". Giving the authority to the DoJ (who is both a partisan, nominated official, and is very biased in the prosecution of those whoa re accused of breaking this law. I don't put any credence in "still take in recommendations from provider input"; I assume Congress and the DoJ can ignore any and all feedback if they choose to make a partisan show of a specific case/issue (and they have when it comes to encryption unlocking phones of terrorists, child sexual abusers, and drug dealers).
