Apple is refusing to comply with court ruling, as they say it would weaken the security on all their encryption key.

Also if they are forced to make a tool for law enforcement in US, then they argue that they would have to allow the Chinese to break their encryption as well.

While I can see how it would help with solving crimes and preventing some, maybe the bigger picture isn't so black and white.

Be interested to see how this plays out.

Open letter from Apple,
