A provocative thought experiment: are you more annoyed by retailers recommending a product you just purchased from them, or a retailer recommending a product you probably will need soon? In a world blanketed by advertising, I would rather see relevant advertisements than be bombarded by garbage. Maybe I will get a deal, maybe I will discover something I like, maybe I will ignore it... but the spray-and-pray untargeted advertising that tries to advertise arthritis medication to me as a 31-year-old man is guaranteed only to annoy.
> Maybe I will get a deal, maybe I will discover something I like
This is what the ad industry exploiting the fear of missing out [1] looks like when they tout the virtues of "relevant ads". You might draw a comparison with casino marketing to gambling addicts, alcohol to alcoholics, etc -- it's rather slimy.
I find highly relevant advertisements creepy. A sort of advertising uncanny valley. I'll take the minor annoyance of a garbage ad bombardment any day over, what is to me, the much more concerning feeling of being surveilled.
