oh for sure, I'm just describing why they're trying to do this - like I think they'd take the problem you're describing as a plus because it's also likely to get in the way of other advertisers. if other advertisers are less effective and you find a way to hurt yourself least, then it's a win because zero-sum Hobbsian arms race that you have to win or your competitors eventually overwhelm you with their own advertising. which is to say, I don't think this is necessarily even meant to work as described.

but that still means they're trying to infest our minds with shit that manipulates our dreams. effective or not, it still sucks. it's going to drive further alienation, probably have serious mental health consequences at a population level, and generally be hazardous to the health of all of us. in a word, hellworld.
