Well I contribute(d) to Tor (in small, almost meaningless ways like translating it and managing the translations), but I never did anything illegal. In fact, I've never even been to the U.S. Why should I be labeled as FBI's enemy if I never even entered the U.S. and when all I wanted to do is to give something give back to the world by allowing the people of my country to browse the web anonymously?
It's not my fault if someone from any country in the world decides to use the project I helped with in an illegal way.
