I'm still failing to see how the original claim, that everyone has to abide by the DMCA, is true. This seems like claiming that everyone has to abide by Thailand's Lese Majeste laws (laws criminalizing insults to the monarchy). Yes people may face repercussion if they have an economic or physical presence in the country. But if they don't, then theres nothing Thailand can do to enforce this law .*
* not without cooperation with other countries at least. Some nearby countries are known to enforce Thailand's Lese Majeste laws abroad and extradite people. But in most countries, this isn't the case.
Again, if a country doesn't want to abide by the DMCA then they don't have to. Extradition treaties and the Pirate Bay do not disprove this claim.
But extraordinary retention is just the fancy word for CIA abduction. So no treaties are in place here.
It's been this way for nearly 20 years.
