The question is how to keep kids off social media. I am very thankful neighbor mom, who bought her son a smart watch and not a cheap android phone. Good example for other kids. It’s clear, that departments with lots of clever people are doing to lock young kids in the phones. And only parents can protect them.
The key is education, you have to explain to your kids how these services works, how they are optimized for content engagement to show ads, how they mine your data, and what kinds of things they should look out for and avoid (like misinformation, catfishing, grooming, viral stupidity etc)
