The funny thing is, the ai-generated engagement is specifically formatted to still be desirable in that situation, because plenty of advertising is already purely to create goodwill.
Imagine that when people start talking about Nestle being horrible to its workers, a "dynamic product ad" chimes in to retort that Nestle is actually great and cares about its workers.
Exactly like election disinformation? Yup, and plenty of companies can't wait to have their own disinformation bot net, sanctioned under the guise of "advertising."
