How much should they be paid for it?
However much they're asking. They put a price tag on it for exactly this question.
In this lens, can piracy be considered a form of civil disobedience?
Not really. Civil disobedience is about refusing to follow a law, not choosing to break a law. There's a difference between the two concepts; one involves going about your day as normal and ignoring laws, and the other is going out of your way to break a law. Piracy is no more a form of civil disobedience than looting a grocery store is.
