Parents understand that they cannot be the sole arbiter of everything for their children. Locking down your children's inputs is not fully realistic. If you remember being a child you remember circumventing your parents at every turn.

And so instead we should expect corporations to fill that role?

Yes. At the tail end of my comment I stated that calls for violence (forced imprisonment) against either CEO (like original poster in this thread) or parents (like me, as satire) for not sanitizing a child's entire life is wrong. Both are wrong. There isn't even a problem here. Certainly not one that requires the use of force to deprive humans of their volition.
