I agree with you. I highly doubt that our economy has enough (product, message) combinations to justify the need for personalization based on more than a dozen attributes.
I will buy X, if I need X. And once I buy X, it's done. For example, I wanted a cordless drill last week. Did the "site:reddit.com" thing (I actually have been doing that almost subconsciously now, as Google results are all trash), chose a drill, and ordered one off Amazon.
Then, after that, what's the point in showing drill ads to me for two weeks?
There's a well known effect in advertising that advertising a product to a person that has already bought that product generally increases their satisfaction with the product and the purchase, and may cause them to recommend the product to others.
Probably that's what they are going for if they're doing it on purpose.

Do you have a link for further reading on that? That's fascinating if true.
It's not supposed to feel good. If 9/10 people have a brief negative thought about the advertising experience and nothing else happens, but 1/10 people happen to have their friend on the phone at the time and makes a referral, then overall that is a win for the brand.
