They aren't require to stick to using a bare copyright license.  They 
could instead make the license a contract (like almost every other free 
software/open source license...), and then there would be no problem 
with prohibiting things that are otherwise allowed under copyright law.

There's a good discussion in Rosen's book on open source licensing of 
why it is best to make your open source licenses be contracts.
