If you use #GMail, #Google keeps records of everything you buy, even if you delete the email receipt, and even if you didn't buy the product from them. Here's metadata from my takeout showing price, delivery address, description, vendor, etc. #privacy
I've been telling my friends this for years, but their lukewarm reaction is usually something naive like "I don't have anything to hide".
@hans that argument has always appeared poor to me as well, and I've generally used Daniel Solove's counter (he's actually written numerous academic papers and a whole book on privacy) anytime it pops up: https://www.youtube.com/watch?v=FqJ8EMwj7zY&ab_channel=TheAgendawithStevePaikin
Daniel Solove: Nothing to Hide, Nothing to Fear?

@zeruch Nice link, I might get that book! I've used several of those arguments in discussions, but somehow I don't seem to be very convincing. Or most of my friends are really dumb, but I like to think they are not.

Fact is that most people don't see any danger other than receiving some well targeted spam. For most people privacy is like oxygen: they will start worrying about it when they notice it's running low.
@hans Solove can be a bit dry to listen to, but his arguments are concise and I think present an interesting bridge between what people seem to get paranoid about and the actual fundamental stuff that should be worrisome. Frankly I'm totally okay with the entire #adtech economy collapsing on itself and something new growing up through the ashes. I frankly don't care about the disruption in the process; #surveillancecapitalism is trash en bloc.
