And it is complete shit. I uploaded a video of my son playing Fur Elise on the piano and got an automated noticed from Google that I had uploaded a video infringing on some company's work. Completely absurd.
When I googled the company's name, I found countless people complaining of the same thing. One guy had a video in which a siren was going off and they claimed that was copyrighted!
People have suggested that there's an anti-intellectual bias ingrained in the American psyche, but I don't think that's actually the problem. It's the assumption that someone else will do the thinking for you that's the real nasty, seedy little heart of the matter.
I really look forward to the gov't expending taxpayer dollars it doesn't have, and endless amounts of energy, chasing down ghosts and persecuting middlemen in defense of trillion-dollar interests. Because the sooner the US becomes the laughingstock of the western world, the sooner it's likely to get its house in order and gag the busybodies, wingnuts, corporate interests and degenerate senators who are creating its current policies.
In fact success is a rare and fragile confluence of many conditions that is hard to find.
Now, when told by the copyright holder that no use of some work is authorized, they can flag all copies of it that they are able to find and match it under the assumption that nothing is authorized. But you couldn't add anything if we assume that every user is lying about being authorized.
Moreover, as was demonstrated in the Viacom case, even the copyright holders get it wrong. In particular, Viacom had uploaded copies of their own works and made them appear leaked. Yet these were uploaded by Viacom itself and, thereby, authorized. They even had to go back and have them put up after taking them down by mistake. And they had to remove them from their complaint after being told of their mistakes. Twice. After doing due diligence with expensive lawyers.
Anyway, what about remixes and magazine photos and quotations longer than a paragraph?
