It's not good in some job negotiations if someone has a very clear picture of what your current net worth and income is. Also in some purchases companies could price discriminate more effectively against you.
Now that's a question I'd feel more confident having answered by an LLM. Personally, I'm tired of arguing with "nothing to hide", which (no offense) is just terribly naive these days.
I find it really weird too, like, haven’t we done this? Also struggle to understand the motivation for arguing from this direction. Do people forget it’s the normal, default position NOT to be spied on?
