Then maybe the business model for these genericas should be toast. No entity has to have the ability to be able to know me in such a fine grained way as to be able to even target me out of context and influence me for consumerist (or even political) reasons.

If I am in the mood of car prOn - show me porsche or stuff. If I ready about python - show me current books on the topic. Or Udemy courses. Or what not.

If I currently read about how to get rid of pimples - show me beauty products.

But don't try to influence me into buying the latest camera gear, when I am interaction with my animal protection buddies over facebook.
