I'm sure the random person violates a number of laws of Iran and/or other autocratic countries with one's online comments. Should these countries serve up extradition papers for them?
While I agree many copyright laws are broken in many ways, this sort of agreement is also what makes the GPL of source code copyright holders enforceable in other countries.
Chinese GPL violators were a big deal in 3D printing a few years ago, with many companies not releasing their 3D printer firmware source based off the Marlin GPL software.
It's been a while since I followed that but it's apparently got real legal precedent now, with a Chinese court fining a local GPL violator: https://segmentfault.com/a/1190000040661920/en
The extradition treaty applies only if a crime is actually committed in a jurisdiction where it is a crime. I do not see this here.
