Tim Cook has sent a letter to Apple employees defending the company's decision to remove an app used by Hong Kong protesters to coordinate actions and avoid police-focused applications.

However, the Chief Executive has been criticised for the fact that the Hong Kong Police's claims are “taking at face value" and are inconsistent with the experience of local international observers.

Cook wrote to all Apple employees today, defending the removal of HKmap.live from the iOS App Store. Cook says: “These decisions are never easy, and it is harder still to discuss these topics during moments of furious public debate.”
