Dick Costolo Takes Over as Twitter CEO

Ev Williams, who took the reins as Twitter CEO from Jack Dorsey two years ago:

This led to a realization as we launched the new Twitter. I am most satisfied while pushing product direction. Building things is my passion, and I’ve never been more excited or optimistic about what we have to build.

This is why I have decided to ask our COO, Dick Costolo, to become Twitter’s CEO. Starting today, I’ll be completely focused on product strategy.

I don’t buy that as an explanation. Why can’t the CEO be focused on product strategy? Seems to work for Apple. What happens now if Costolo and Williams disagree on product strategy?
