So here's Gideon Gallery's philosophy on how the law should work...
A car thief steals a car from Person A, but Person B who doesn't own the car points out that it's stolen. What Gideon would like to have happen in his fantasy... Person B's car is awarded to the thief.
That sounds absolutely fantastic for the thief! But we're not talking about protecting thieves. We're talking about how to wipe them off the face of this earth, and how to make their existence as miserable as possible. We're talking about protecting the property of content creators... not trying to figure out ways to reward thieves for doing something nefarious and underhanded.
Either way, the thief does not own the car. The thief has no claim to anyone's car. And the thief should be reprimanded.
