Take, for example, unauthorized fan translations.
Fan translations are typically given the benefit of the doubt because none of the copyrighted material is distributed by them (only a differencing patch to apply to it), and while some will take advantage of it to play illegally this is not their intent; piracy groups, however, release a self-contained, ready-to-install copy of the game along with the crack for the explicit purpose of playing illegally.
If the pirate groups were releasing a diff-only patch for the protected EXE--with acquisition of the actual EXE left up to the player--that would be a different matter, but that is simply not what they are doing.
I hate how people seem to think nowadays that every idea needs to be owned as if it were some law of the universe. This goes for crackers and the like just as much as the big guys, and I think this thread shows that self-centered hypocrisy involving claimed ownership is not limited to the latter.
It's not other people who have bizarre views about idea ownership, it's you!
Copyright is an international concept that has been around for a very, very long time (the mindset behind it existed even before the laws themselves). Anything that isn't explicitly copyrighted is wide open for someone else to take (legally, if not ethically); while some people deliberately leave their work open for re-use under an "open source" or "copyleft" license this sharing mentality is not held by the vast majority of content creators.
If you want copyright law changed, do something about it. People who changed laws didn't do so by sitting on the sidelines and complaining about how things should work. Complaining that everyone is saying something is normal when hardly anyone actually considers it abnormal is a waste of time.
