I agree with the OP that the ban is woefully undemocratic, and that banning it for children only is a grave misstep.

I think what they should ban instead is recommendation algorithms. If I subscribe to a source, and explicitly unsubscribe from another, it should be illegal to withhold some of the first’s postings and shove the second’s in my face. This should be a no-brainer and has nothing to do with the age of the user; but it's easier to just ban the people who, as OP correctly noted, have no representation and no recourse.
