Uber COO and CMO to Step Down

This is really weird to me. It seems strange for a CEO to effectively fire the COO and CMO because they want Operations and Marketing to report directly to the CEO unless the company is in serious trouble and needs a single authoritarian leader to set direction across very different departments. Does anyone else have more info on this?

From the top of the article:

>Now that the company is public, CEO Dara Khosrowshahi says he has more time to be involved in the day-to-day operations of Uber’s core businesses.

Ummmm what? Isn't it normally the opposite?
