How is it justified? Just because it's a law doesn't mean it deserves to be followed. Anime downloading laws are unreasonable and virtually unenforceable. This leads to people inconsistently being "caught" and probably serves as a deterrence to no one except the guy who ends up having to pay the fine. (And he probably won't stop illegally downloading, will just make more efforts not to get caught).

If Funimation wants to make money they should figure out how to work competitively while still making a profit in the current times, instead of just suing everyone and their mom.
