I wonder how possible that would be given the quote in the Jobs biography:

"He told Isaacson that Ive had 'more operational power' at Apple than anyone else besides Jobs himself — that there's no one at the company who can tell Ive what to do," the report said. "That, says Jobs, is 'the way I set it up.'"

The only actual legal structure protecting Ive's position at Apple is one in which Cook voluntarily complies with Jobs' stated wishes. That is to say, there is nothing stopping Cook from firing Ive tomorrow, changing his job title or control inside the company. Jobs may have also secured the board's agreement to protect Ive, but that too would rest merely on their voluntary compliance with such. In the corporate world, there's no such thing as a truly untouchable employee. The CEO, the board, or shareholders, someone can always get rid of you.

see Steve Ballmer

What talent has Ive driven from the company apart from Scott Forstall and this guy?

Jon Rubenstein had plenty of conflict with him (via the Jobs and Ive biographies), and Tony Fadell as well [1].

He may not get on with Ive, but Apple Maps was Forstall's downfall.

That’s enough.

How many people did Steve Jobs drive from the company on his return? (answer: the CEO, the whole board, and 1000's of employees)

At some point the Western intellectual canon of rhetorical tropes and logical fallacies will need to be expanded to add the "because Steve Jobs" fallacy which seems to justify anything on the basis of Steve Jobs having done it (without regard to context, or that the party in question is not Steve Jobs)

The point is that Jony pushing a few people out* as he takes control is hardly cause for concern.

What would be cause for concern is if the people obviously responsible for Apple, I.e. I've and Cook, were timidly playing corporate politics instead of decisively leading.

(* although it seems that the story of Christie leaving because of disagreement with Jony is actually a fabrication)

[edit: downvote away, but it would be interesting to know what you disagree with)

It's a bit hard to judge from the outside isn't it?
