Arguing about whether this is good or effective for kids or not is irrelevant. This isn't about kids at all. It's about surveillance.
Regardless of the underlying motives and surveillance outcomes, it will surely affect the kids too. So it's worth discussing.

This is obviously about kids. The problem is it requires surveillance. You don't get to decide what it's not about.
Do you not see that the largest companies on the internet are also surveilling everyone and that the massive troves of data they're collecting about their registered users and even non-registered users is directly and indirectly accessible to governments around the world?
