This is the outcome of lack of competition.

Also, Apple is not enthused about anything that might limit the ways in which a device is used. The whole point is that everything they do is focused on finding more and infinite ways to make a device used. Constraining use is deeply against the DNA of everything they are actually aiming at. There seems to be a real, deeply ingrained unwillingness to implement things that might reduce unfettered usage.

Truly this is politics. In politics, you say what people want to hear but do whatever you want. That's what Apple does - positions the iPad as kid and family friendly but just does what it wants.
