Well, this one was patched (or more accurately, undone).  Perhaps.  Maybe.  

How many other "paid defects" do you estimate there are in Microsoft Windows waiting to be exploited when discovered (or disclosed) by someone other than the "Security Agency" buying the defect?  

Almost certainly more than just this one ... and almost certainly there is more than a single "payor agency" independently purchasing the deliberate introduction of code defects.
