What is there to learn? Like all rulers since the dawn of civilization, they are afraid of the unruly masses, and want to keep tabs on them.
The fact Backdoors are useless or even counterproductive against criminals is irrelevant, that's not why they're here. They allow the governments to sleep better at night, and thus are perfectly doing the job they were meant to do.
Note the tearful "somebody please think of the children!" argument, a clear sign they have no real arguments to back up their project.
