On a serious note, it does remind me of that time police arrested a man on suspicion of a break-in, because he was riding his bike in the neighborhood at the time and Google recorded it.
That could include such authorities, manipulating or interfering with events and lives, more than anybody would think possible or should be legally allowed.
What might be a good example?
Google and other authorities having such access to so much data about individuals, means they can know of relationships, that the interacting individual parties involved don't know about each other. So, if a wife were cheating on her husband, that can be known. A line can be crossed, where information is leaked to the husband, in various ways. This of course is just a "theoretical" example, of many other kinds of possibilities.
Access to private and personal information is its own kind of power, that can be easily abused under many gray areas, and under all kinds of pretexts and weak justifications.
Do people who see ads get ads based on where they've been by the way?
Seriously, they know every time you pick up your phone. Where you shop, how much you spend, if you miss a stop in the highway, if you text your parents happy birthday, if your heart rate increases when you’re around a particular phone. They quite literally may know your gay before you do.
I wish that was pure /s, but the amount of "Ask HN: Google banned me or my business for no obvious reason" is really staggering. (n.b.: Of course I'm talking about the old Google of 2022, not about the glorious overlords that Google since has become; all praises the holy trinity of Android, Google Search and Google Glurp for Glorps! Please don't ban me.)
On some level alarm bells are going off.

Only… they gave that information to government (supposedly post-analysis and anonymized). Regardless the data was quite literally used to “track and trace” then as a mechanism / justification to place you under house arrest.
