I said "actually closing" mainly because they cut off the ability to create new members. If they wanted this to be for publicity, they would still be taking new members to keep the count going up and up...
If they really cared about the power of the media and the ability of the VMK community to cause an uproar, it would have kept the new member option open...to see what kind of impact the announcement had. I'm guessing they could have had thousands of new members in a short period of time.
