Ah, that's not my understanding of civil disobedience. I prefer this definition: "civil disobedience is a public, non-violent and conscientious breach of law undertaken with the aim of bringing about a change in laws or government policies" (https://plato.stanford.edu/entries/civil-disobedience/)

I suppose the piracy aspect might not be public enough to count as civil disobedience though, unless you count as public the noticeable cumulative effects of all piracy.
