@hansw Thank you for the instructive comment.
You are totally right, education about privacy in general and cryptography in particular is the way to go.

Mea culpa, I was not specific enough. My intention was simply to emphasize the benefit of using open source operating systems (and software in general) to avoid issues like this:
Apple knows when you’re at home. When you’re at work. What apps you open there, and how often. They know when you open Premiere over at a friend’s house on their Wi-Fi, and they know when you open Tor Browser in a hotel on a trip to another city.

Of course this is not exclusive of Apple computers, we have the same problem (even worse I would say) with all modern smartphones and portable devices. And I think the level of privacy-awareness of the society is far from healthy.
