Consumer Reports and Reuters don't attempt to manipulate stock prices. You might disagree with their conclusions but you're obviously wrong about their motivations.

You can learn a lot by observing the gaps...
It seems natural and very above board for Cruise to want to spread this good review, though they cannot use it in advertising.
