The article summary pretty much says it all:
“If market expectations are any guide, though, the United States will likely end up allowing its citizens to gamble online. In the hours after the WTO ruling was announced, stocks in online gaming companies lifted. Investors clearly see the writing on the wall, even if the U.S. government does not.”
US law is being overturned by international agreements. Troubling on the one hand, and justified on the other. The congress snuck in the amendment outlawing online gambling in the ports bill last year. An action that should not be allowed to stand. Downsize DC has something to say about it as well.
