If it really was Steve Jobs's "fault that the MobileMe launch went so poorly" because of "the system that he created," and her team was really as "completely kick-ass" as she says it was, then why has Apple had so much success with so many projects run exactly the same way?
The problem with MobileMe was the engineering management, not the system.
If anything this shows how vulnerable the Apple "system" is to the quality of the people they hire, and why they spend so much effort trying to hire and hold on to A-grade people. That just doesn't jive with the tired lore of Jobs being an asshole all the time. They wouldn't be able to hold on to folks like they have.
