It's OK, Sir Jony Ive still works at Apple!
Sir Jony Ive - he's a Knight, don't forget! – did disappear from Apple's executive bio page this morning, but don't worry, he still works there. He's back on the top line, and presumably whoever accidentally deleted him either feels really dumb or has since been fired. It also didn't happen everywhere, in the UK he was present the whole time.
If Ive had left Apple, this probably isn't the way it would have been announced. But he hasn't. He's still there, and will continue to design killer products!
