Apple CEO Tim Cook commented on the dissatisfaction of many users with the closedness of iOS for installation
According to the head of Apple, iOS is 15-47 times lessis at risk of being infected with mobile viruses than Android. This is achieved due to the fact that Apple's OS is implemented as an ecosystem, and the installation of third-party applications can become a loophole for viruses and, as a result, hackers.
Cook named installing third-party IPA packages oniPhone and iPad bypassing the AppStore by driving a car with faulty belts and disabled airbags. And if some users like this alternative, they should switch to Android, which, according to Cook, is less secure than iOS.
