What this essentially means is a move to Android for criminals, terrorists, and anyone that wants privacy (since Android allows installation of apps that have not been approved by a gatekeeper bound by the laws of the countries it operates in, whereas iOS does not by default). Open source Android apps with strong encryption will be built in countries without such laws. All of this will likely be the downfall of a few lazy drug dealers that don't want to give up their iPhones, but since the cat is out of the bag and apps with end-to-end encryption already exist and will continue to be built, the governments making these moves will not actually catch any reasonably intelligent terrorists that install and use these apps. They will, however, gain exactly what they want: the ability to conduct surveillance on most people in the world whenever they want.
