What’s the hard numbers for the scope of this threat? What are the case studies of prior instances of enterprise certificate store exploits? The threat vector of third party app stores, whether from rival FANG big companies or from phantom enterprise cert app stores, still makes assumptions on user behavior. Good luck getting even tech enthusiasts to be quick to jumping on rival app stores, and dealing with the whole rigamarole of setting up new memberships, payment accounts, and purchase histories. Much less the so-called “grandma” demographic. The App Store would still be preeminent even if iOS was to open up to sideloading. Simple consumer behavior would prevent masses of users from departing from a system that’s over a decade old. Thus that vector is mitigated.
