No idea if they can, but there are better ways to deliver personalized ads without spying on users; for example I am interested in some areas (motorcycles, home improvement/DYI, indie music) and not at all in others (fashion, clothing and perfumes).

I am no Meta user at all, but if I would be then I would love to set my ads preferences and get only adds that have value to me and to the companies paying for these ads and get right of the ones I never act on. That brings a lot of value for all parties.
