First problem is getting the people talking to their children to care about privacy. I’m a grown-ass adult and it’s hardly at the top of my priorities, regularly using Google services with Bing as my search engine to get me Microsoft Rewards points I can blow on games.
It’s going to be even tougher for a kid whose friends are all on TikTok and who has no money (and would probably be delighted to learn about services that pay miniscule amounts for data, like the Amazon and Google Play ones in addition to the Microsoft one).
