A simple first step: send an article on digital privacy, that you like, to your network and invite them to get back to you with questions they have. A possible start: EFF have an excellent privacy hub https://www.eff.org/issues/privacy
I have taken a case study with my teen about people loosing careers after facebook flame-wars; and being hauled in by police on face-recognition and geolocation data. We have a discussion at least once a month about the cyber-dystopia we find ourselves in.
As I posted before, I'll just leave this here:
1. "It turns out that Facebook also buys data about your offline purchases. The next time you pay for a burrito with your credit card, Facebook will learn about this transaction and match this credit card number with the one you added in Messenger.
In other words, Messenger is a great Trojan horse designed to learn everything about you."

2. "Google now knows when its users go to the store and buy stuff.
Google has begun using billions of credit-card transaction records to prove that its online ads are prompting people to make purchases – even when they happen offline in brick-and-mortar stores [...] Privacy advocates said few people understand that their purchases are being analyzed in this way"

Consumer data is the gold the consumer appears to be giving away, unwittingly or carelessly, regardless of the regime or geographic location.
