It can't.Again, though, how do we know this for a certainty? This is the popular opinion, but I could easily see WotC legal saying that this policy applies to all fan sites.
I can't just write a license and claim it applies to what you do and then sue if you don't comply with it, possibly not even knowing the license ever existed.
They could use the terms of their license as a guideline to know when they start legal actions against a fan site that technically violates copyright or trademark laws - but that would not give them any more "power", since they still need to find/show the violation of laws.
