This is top level enshittification. You're showing the user an ad that is, as OP says, the opposite of what they want, and then charging Truth Social for the impression. Magnificent!
'Targeted advertising' is shockingly untargeted. As the underpinning of our digital economy, the value of online advertising is dangerously overinflated.
I worked in advertising for over 10 years before a career change. I saw how much money was wasted on programmatic digital advertising. I'd recommend checking out the book, The Subprime Attention Crisis
The only time I ever click on an ad for anything is because I want to see exactly how much they are charging for whatever clearly ridiculous thing they're advertising. Meaning I was never planning on buying it. Thankfully, that is rare.
