No, it is
not your whole point. They are being sued based on the
contents of
the file when the file with masquerading as something completely different.
The fact that they intended to violate copyright in the first place is
irrelevant. In this case, the files were masquerading as copyrighted works that
this plaintiff
does not hold the copyright for. It would be up to the
copyright holder to attempt to sue these people, not someone completely
different just because it will 'teach people a lesson.' This kind of 'teach
people a lesson' bullshit is no different than when the DoJ was trying to say
that violating MySpace's Term of Service was tantamount to Computer
Hacking/Fraud because there were no other laws to punish that lady that caused
the student to commit suicide.
The idea that someone should be punished for something they didn't intend to
do, even though their original intent was bad in the first place is an abuse of
the legal system, IMO.
It's probably easier to boil it down to this:
The user is being sued for 'violating the copyright of copyright holder X' not
for some nebulous 'violating copyright but it doesn't matter what copyright'
infraction or else I could sue you for violating someone else's copyright.
Therefore the question should really be, "is it reasonable to have expected the
user to know that they would have violated the copyright of copyright holder X
when they downloaded/uploaded that file?" You're trying to phrase the question
as, "is it reasonable to have expected the user to know that they were
violating any copyright when they downloaded/uploaded the file?"
