Even us smarties don't "know" anything. Apple has been doing fine in the past with these execs. If there is discord, it's not affecting sales. Record revenue, record profit.

In the future there is now some uncertainty: was Scott Forstall the key to iOS? Is Jony Ive a good UI designer? Will Bob Mansfield retire again next year? If you don't like that uncertainty, it's a good time to sell.
