Even my mother, in her 70s, who somehow always manages to have a new virus or piece of crapware on her laptop every time I visit, knows about the importance of this thing called "privacy" and had no trouble grasping the idea that everything she shares on FB is recorded and used for advertising.
It's not a hard concept, and it's not just tech people who care about it. It doesn't require any knowledge of tech to understand.
On the other hand, she knows how to use FB messenger and my efforts to get her to switch to email/telegram have just caused confusion so far.
