"Photographers can say, for example, if they're only happy with non-commercial usage or specify what kind of credit they want to receive.

But the vast majority of licensed images are up for grabs commercially – which means that Flickr is perfectly within its rights to start flogging them off."

The CC licenses are irrevocable - once you've chosen to use a CC license you cannot revoke it. One of the big reasons you should never adopt it for your work.
