So... I'm not sure that ads are the center of negative consequences... AND it's not actually true that advertisements aren't considered speech with first ammendment protections in the USA, it is (although it has LESS protections than some other speech, and can be regulated, probably including in this way)...

But on top of all of that... what is an "ad"? Is it an "influencer" who is getting paid to promote a product but doesn't actually disclose that? Which already violates FTC regulations, and we aren't even managing to enforce the regulations we've already got, cause this is pervasive.
