I have always been curious about this. Did you get them to use other services or did they stubbornly refuse and you just accepted it? I am talking using Chrome, using Windows, using social media like Tiktok or Facebook or Instagram, etc. Bonus points if you have kids because that is even more work in the privacy realm
Got the wife a grapheneOS pixel, she likes it and the adblock as well. But can't let go of Facebook , Spotify ,WhatsApp etc. Small steps
That is still a huge improvement over using a regular iPhone
