U.S. settles some internet gaming disputes

Radley Balko reports that EU, Japan, and Canada have settled (via Midas Oracle). His parting thoughts:

So the tens of billions the U.S. government is paying to settle the trade dispute is not only to preserve the gambling ban, it's to preserve the congressionally-granted monopoly on online wagering for interests with more political clout than poker players.

Finally, U.S. Trade Office flack Gretchen Hamel apparently told Reuters she "isn't going to get into" the terms of the settlement. Pardon? Is the settlement not being paid with public funds? Aren't the people who negotiated the settlement employees of the U.S. government? On what grounds does the U.S. Trade Office feel it's entitled to withhold this information?
