> The link you've added seem mostly for software tools that block social media
There are articles, communities linked on privacy, surveillance, etc issues.
I think the first step would be to self host your own social media and other stuff (next cloud?) with the family. Although, not every kid will be interested but I presume at least one would be curious in your case. Start it as a hobby on a weekend and invite them. Get s raspberry Pi and it will be a fun tinkering experience.
