Like it or not, neither modern media nor the MPAA introduced this usage of piracy. It has been around and part of legal discussion about intellectual property since the 1800s:
"I know patentees are much troubled with piracies upon
their inventions" (Irwin v. McRoberts 1879)
"he has a just defence, and is not a willful pirate
of the plaintiff’s invention" (Goodyear v. Dunbar 1860)
"I know patentees are much troubled with piracies upon their inventions" (Irwin v. McRoberts 1879)
"he has a just defence, and is not a willful pirate of the plaintiff’s invention" (Goodyear v. Dunbar 1860)
and so on...
