> Ads are no more psychological manipulation at scale than words in general.
"no more" in your sentence implies the impact is roughly the same (not that I agree with your premise that all communication is manipulation, unless your definition of "manipulation" is so vast as to be useless).
No more does not imply equality, just that it's not greater than, which is simply the truth. Advertisements are not inherently more manipulative than words in general.
If the subject was propaganda, instead of advertising, then sure.
You have weighed "words in general" against ads. For me that is comparing an average with those ads. The average of generally used words/speech is very, very far from Trump's tweets and similar communication, IMHO.
