You're assuming that turning off ADP in the U.K. is sufficient to appease the British Government. The Investigatory Powers Act can also be interpreted to give the U.K. the right to ask for encrypted data from users outside of the U.K. (see Apple making this exact point in a filing here [1].) Turning off ADP in the U.K. doesn't end the controversy if that's what's at stake.
