That must be the poster child of the most boring and meaningless accusation thrown around new technologies (after the data center water scare, which was just plain bogus). We've heard this non stop since Cambridge Analytica nothingburger. It's all noise distracting from the one meaningful aspect of it: marketing to people is electoral manipulation, and since that's unquestionably allowed, the horses have left the barn long time ago, and futzing over the AI barn door control makes no sense at this point.
If anything, the problem that this is effective in the first place is the one to address - this translates to people still believing anything politicians say, despite decades of continued proof all the campaign promises are just plain bullshit, and stated beliefs are situational and not principled.
For a more immediate example, look at Russian weaponization of social media in Mali for a pro-russia, anti-everyone-else narrative. Often deployed against a population that has a much greater level of credulity of anything they see on social media, and lack of inoculation against it by multiple years of seeing artificially generates nonsense.
