The way I understand it people need special licenses in order to operate in iran (meta) and therfore the probability of being sued is very high?
The Treasury source they cite (https://home.treasury.gov/news/press-releases/sm0322) seems to check out:
> Section 560.540 of the Iranian Transactions and Sanctions Regulations (ITSR), 31 C.F.R. Part 560, authorizes the exportation from the United States or by U.S. persons, wherever located, to persons in Iran of certain publicly available, no-cost services incident to the exchange of personal communications over the Internet and certain publicly available, no-cost software necessary to enable such services.
extra territorial example: it may be a crime to do things/speak ill of a foreign government. If you lived there you’d get arrested. What if you did this while sitting in your bedroom overseas?
But then in that sense Iran can do whatever it wants once they get their hands on you, laws or not
E.g. BNP Paribas, a French bank, were fined for doing business in Iran. A Ukrainian was extradited from Poland to the US for hosting a pirate website.
