I think the reasoning behind "Privatyke" was that "privateer" is another name for a pirate.
Privateers were employed by whatever Navy - they often acted as pirates, but only towards enemies of whichever royalty employed them. A Spanish privateer would never attack a Spanish merchant vessel, and would even defend one under attack. Pirates had no such limitations.
That's neither here nor there, though. Great jobs on the sprites so far, guys!
