The problem is that some developers abused this facility, which avoids Apple’s app review process and, in some cases, led to the evolution of grey markets engaged in the distribution of pirated games, porn, or gambling apps on iOS. The latter is almost certainly the kind of Wild West chaotic reality that would be encouraged were Apple to be forced to permit sideloading of apps without restriction on its devices. This isn’t entirely new. Until now, developers have been able to share beta apps and test software internally using TestFlight and the Developer Enterprise Program it allows large organizations to develop and deploy proprietary, internal-use apps to their employees. (Educators, researchers, and event organizers also benefit from unlisted app distribution.) What this means is that a business that has built its own proprietary ordering-and-stock-control app, for instance, should find it easier to furnish teams – particularly remote teams – with that or other apps they need.
