To my mind piracy is more of a security issue than privacy is. Pirated software may not be updated and patched, leaving it vulnerable to be infected and pass on infections. In this, some figures are mentioned for China: There's hardly any visible anti-piracy effort in India and all the PCs I've seen in homes are pirated. A somewhat tangential point is whether "market share" distinguishes between legitimate and pirated software. Ironically, a particular browser apparently got a leg up when China's weight in the computation was hiked.
