Too many here are not getting the use case for this, equating it to plain 'thievery'. This seems like a pretty neat research tool, that does what vmware/vbox/parallels do for desktop virtualization.
Regardless of the turn out for this, Apple really just wants to control how people are able to do security research on their devices. Considering how things went this past summer for webkit security and their response and the mess that has been the current 13/15 releases, they probably should do a better job opening up the system for security research. (yes I know about the recent changes to the bug bounty program)
