> Anyone (especially the HN crowd) should know they have the data, and if you think they're not carefully analyzing it behind the scenes (like every other tech company who has your data), I've got things to sell you.

That's the creepy bit. Who owns that data? I want to live in a world where I own my data, and it can't be used for creepy purposes like this, or to extract additional value through arbitrage based on asymmetric information availability.

Well In this digital age, we do not own the data even if we are generating the data. So I would not go to extreme telling companies not to use my data for any purpose but I would definitely like some assurances from them not to use for such creepy and unnecessary means. Time and time again, we are seeing companies abusing our data be it Facebook for manipulating news feed for experimentation or Uber for such nonsensical studies.

You would have much more control over your personal data in the EU. Companies are required to share it with you on request and are subject to limits on how long they can retain it.
