It's ironic: Most of you desperately want to unseat Facebook, and this is a strategy toward that end. What do you think will happen when those children grow into teens?

If Facebook seems draconian, this would be an opportunity to build something better from first principles. It's a positive plan, not malicious.

I'm not sure Facebook has the ability to pursue this even if they tried. They have too much political inertia for people to trust them with a kids-focused Facebook. That means all someone needs to do is build this, then refuse to sell. Checkmate.

It won't be easy, but two decades is a long time. And that's the timeline to slay a giant.
