I think it's more reasonable to assume that

Wikipedia (which shares many features with Google, Yahoo, Twitter,

Facebook and other social networks) has been the subject of this kind of demand than that it hasn't. No one with direct knowledge would be able to do anything other than deny it, but we can easily see why data held by Wikipedia (including partially anonymized e-mails, file

uploads, talk page communication, etc.) would be of interest to intelligence agencies.

The capacity of the Wikimedia Foundation to keep a secret of this nature is low. Simply too many outlaws; something NSA could probably figure out; they are not called intelligence for nothing.
