Citing the dangers of “sideloading”, Apple and Google defend themselves by saying their app store policies are necessary to protect their users. But while sideloading can be very risky, it can be done securely through the use of time-tested and effective cybersecurity technologies.
Apple attributes iPhone security to its "walled garden" approach. Among other claims, Apple says that an Android device is up to 47 times more likely to contract malware and that allowing app sideloading would attract a wave of cyber crime to the iOS platform.
