Much of why it's not effective in what it pushes as "correct guesses" is because at best those guesses are built via messes of studies, with the same degrees of obvious flaws as this one https://assemblag.es/@theluddite/114101071020285137
So it's definitely tracking/data mining you but as ridiculous as the modeling is, there's not much of a chance it'll ever give you something you actually want.
*I'm among the majority of this trend with you btw, as amongst the most common add pushes I get is for "discount airline tickets/travel", international mostly when I've never had an adult passport & doubt I'll ever go on an airplane again (it's been over 20 years since I've been on a plane).
