This is a simplistic, yet common take. Privacy is not a zero-sum game. If it was, entities that valued your information wouldn’t construct systems to constantly scrape it from you.

As long as you engage with society you will always be generating new information, even it’s as basic as confirming that old information is still correct. That means it’s never too late to adopt privacy practices.

Isn’t it still useful to stop leaving any further footprints?

Sure, Google might know I like to read classic literature, but maybe one day I’ll switch over to some other category of books; isn’t it advisable to not tell Google about this switch? People and their preferences change, and advertising data is useless if not up to date.

Commenting because occasionally I also feel this way - you’re fighting against conglomerates who employ a lot of people, most of them the smartest people in their field, to hone and polish the information they have about us. What could we, as a layperson, even hope to do against this much opposing current? But eventually I come around to realise that we too are slowly getting better at this, that we also have smart people fighting on our side.

I went outside yesterday, neighbours security camera would’ve seen me. Therefore my privacy is broken so I may as well not bother with clothes, or locking things, or anything really.
