Why is this even a subject for discussion? A typical HN user already knows about this, while the general masses don't give a f* about their privacy.

Also, for the most part, FB is not getting your data without your permission(like a surveillance company), rather, it asks you to give it(eg: upload contacts so we could find your friends), or people voluntarily give data to it(eg: uploading selfies, with location and time metadata as bonus).

There are only two things of concern here, 1. How to make more people aware about the privacy implications of their online actions. 2. How to make these firms more responsible for properly protecting the data they have.

Regarding #1, when I told people about myactivity.google.com, at least one person switched to DuckDuckGo(although I don't know if he sticked with it). Attempts to make people switch to Signal have miserably failed, forcing me to use WhatsApp as well. No one ever quit FB though, rather they got deeper into the rabbit hole by using Instagram as well.

Regarding #2, countries should learn from EU and make stronger privacy laws.
