I'm starting to think Apple has found its first viable post-Jobs narrative.
This is all a waste and show off as far as I'm concerned until they go open on everything. With this move, they will also waste very valuable developer's (crypto experience ain't cheap) skills.
BUT Apple appears to be effective at keeping the contents of smartphones out of the hands of police and prosecutors and out of the courts. If you can't distinguish between those levels of protection, you are allowing the perfect to be the enemy of the good.
