There is no such thing as anonymized location data when you have the location of something where and when they sleep and work.
It's a rhetorical fiction the ad industry tells itself.
I think this begs the question of what anonymous data means. Sure my visit to HN is "anonymous" in that it doesn't say "abustamam visited this site" but piece together all the other visits that have my "anonymous ID" then eventually it paints a pretty nice picture of who I am.
And with LLM’s now it’s easier than ever to piece the parts together. Companies were doing it before we even knew what LLM’s were capable of.
Edit: It's a rhetorical fiction the ad industry tells us.
Right, there's probably no other phone in the world that typically stops for hours within 1000 feet of my bed and typically stops on Monday-Friday within 1000 feet of my work-desk.
