You keep using that word, I don't think it means what you think it means.

Piracy is not a crime, much less a serious one. Murder, for example, is a serious crime. Please don't spout nonsense. Copyright infringement is a civil offense, not even a felony.

That is not to say that what Canonical did - if the accusations are justified - is ethically sound. But please don't spread the bullshit propaganda of certain industry representatives.
