In “how to legally steal” by shounic on YouTube, it's claimed that Antigua was awarded by the WTO a suspension of obligation to United States copyright as a remedy for the U.S.' treatment of online sports betting, which was supposedly "unfair" under a trade agreement:
The interesting part, however, is what the [Special 301] report doesn't mention: this tiny island to the [east] of Puerto Rico has a right to disregard Intellectual Property obligations to the U.S.
In 2003, Antigua appeared before the WTO and argued that [the U.S.'s treatment of Antigua-based sports betting sites] was unfair [treatment of international goods] and therefore a violation of the GATS. … The WTO basically handed America the L[slang] … in the official concluding remarks, the judging panel notes that … because [the U.S.'s sports betting] regulations were interfering directly with their GATS commitments, they rule in favor of Antigua. … The WTO gave the U.S. until April 2006 to amend its regulations to conform with their GATS schedule; the U.S. didn't bother, so, in December of 2007, Antigua requested and got authorized to suspend their obligations to American intellectual property.
Sadly, the YouTuber did not provide any bibliography, so following up on this was annoying and difficult.
According to this equally poorly-cited article from The New York Times, Antigua really did seek this remedy, but I couldn't find anything confirming it actually got it.
As a piece of indirect evidence I found: Antiguan ccTLDs are available to foreigners, but at a steep premium ($75–$142/yr) compared to most open ccTLD registration costs (which range ~$15–$40/yr). This seems somewhat to suggest their value for "bulletproof" hosting, though I'm not familiar with the online piracy scene enough to say if this is actually the reason.
