Restricting advertising that is deemed harmful is not unprecedented, for instance tobacco ads in much of the world or prescription drug ads in sane countries. This doesn't even restrict any new kind of ad, it just opens these platforms up to liability for the ads they run. Seems pretty reasonable to me. It means if my system was exploited via an ad on Facebook[0], I can sue Facebook for showing me that ad. [0] Situation is hypothetical, I don't actually use Facebook.
