Ive leaving is a HUGE risk for apple. If he goes others inside will follow too. Apple was Steve Jobs, Jony Ive and Scott Forstall. 2 of the 3 are gone. You see the result. Jony leaving would be the final nail in the coffin.
The board needs to replace Cook with somebody like an Elon Musk. A hard driving visionary who actually speaks to the press. Unlike Cook, Musk lashed out at the NY Times when they slammed his product and said the battery died during normal use. He could have pulled a cook and stuck his head in the sand. Instead he came out with the truth and proved the reporter was fudging things
If apple does not get an outspoken, visionary leader they are doomed. Cook is a supply chain guy and 180 degree opposite of what apple needs. I'm out of the stock but sad to see a company that once made leading edge products fade into the ether.
