My guess is the listed countries haven't paid the
mordida to the right people in the U.S. government.
Note this from the linked article:
. . . Some of the international giants having the wherewithal to deploy such assets are combining forces to meet the May 31, 2014, first reporting deadline . . .
What are the odds that someone in .gov will determine that US companies "combining forces" this way somehow constitutes collusion, violating anti-monopoly or price fixing regulations?
