As far as I understand international cases, in most countries they are only enforcable if the things that you did were also illegal in your home country. So if it's OK to do this in the us, it doesn't seem to be enforcable here (but IANAL).

No kidding, you aren't a lawyer and this is completely wrong. If you read the original piece, the case would have gone to Canadian courts. Courts use the law of the land they are in, they do not make "exceptions" for people who live in countries with different laws.

There's a difference between a court delivering a judgement and this judgement being enforcable. I never said that the case wouldn't go to Canadian courts. Just because some foreign court says you're doing something wrong doesn't mean that your home country automatically agrees with that decision. Many countries (maybe except the UK) won't care that much unless what you did is also illegal according to their law.
