I didn't say in, I said during. He was pushed aside DURING the PR campaign, not IN the PR campaign. If they were upset about how this movie performed (Why would they, it is a critical and financial success) They would do a similar thing they did with Edwards, announce a writer for Johnson's trilogy, and keep him as Director, it's a soft change, but isn't a shot in the foot.
The point is, there is no evidence that Lucasfilm is unhappy with what Johnson did.
