Both Apple (with iOS 8) and Android (with Android Lollipop) have begun encrypting their operating systems, making it supposedly nearly impossible for users to be spied on or for police authorities to take data from the devices.
Baker says that encryption was the downfall for BlackBerry (although, I would disagree), as encrypting user data limited its business in countries that require government oversight such as India, Arab Emirates, China and Russia. "Blackberry pioneered the same business model that Google and Apple are doing now - that has not ended well for Blackberry," added Baker. "They restricted their own ability to sell. We have a tendency to think that once the cyberwar is won in the US that that is the end of it - but that is the easiest war to swim."
