I think you should also include restrictions in your EULA to prevent people from publishing statements about your code quality too. Very few are qualified to measure it, and spreading potentially false information can hurt a business. I can think of several other items that have limited expertise in evaluating and could cause negative PR harm if done falsely, so you probably should just enumerate those in the EULA too.

Also, I gather from your comment in support of these restrictions, they are more than boilerplate and you will pursue offenders.
