One question I got at LCA was what stories in popular culture we can point our chosen friends and family at. It's not enough to get them to watch these shows and movies. We need to be able to point at the real life news that have similar things happening so they realise it's not just Sci-fi. We need to have gentle empathic conversations with them. We can't argue or harrang them. I know you aren't hassling your chosen ones. But there will have been convos where they feel attacked.
So we try to change the narrative, we change our language to "I feel it would be better to consider..... , rather than why use Facebook..." as an example. You want to start by spending time and perhaps suggest binge watching some movies and TV series. You can take breaks and gently start discussing the deeper themes. It needs to be organic and we need to actively listen to what our loved ones say.
Then we can counter the narrative, not counter attack. We need to change hearts and minds. It's a gradual process, FLOSS Advocacy is a constant never-ending process. Over 20 years of watching MS and Linux arguments online have convinced me about that. Watching distro communities grow by community advocacy beyond RTFM has demonstrated that as well. We win by showing empathy and providing help through good documentation and helpful community interactions with newcomers.
So here are a few TV shows and a movie at the top of my head that can illustrate what we are talking about when we worry about mass surveillance and data collection. Please feel free to add to this. I'd like some new stuff in my watch queue, even if it's not in English. I'm learning some additional languages so I love foreign language content. :
