Who cares, Apple as any other US company must cooperate with "cops" or 3-letter agencies.
Not publicly, of course.
Ask yourself, do you really own your device? Can you access kernel? Can you flash your own firmware on your device? No?
Then you DON'T own it.
Apple has repeatedly shown - as in this case - that when police are able to find a way to use their subpoena and coercive powers over Apple to subvert a user’s privacy expectations and extract data from an iPhone, that they see that as a failing of iOS and are willing to fix that bug.
In this case they are patching out a data extraction path that was exploited to access data a user thought had been deleted.
