Bios_Hakr points out an ironic use of the DMCA: for the second time, a video tutorial on fair use that Larry Lessig uploaded to YouTube has been muzzled. This time the sound has been pulled from the video; last time the video was taken off of YouTube. (Video and sound for the new "webside chat" can be experienced together on BlipTV.) Both times, Warner Music Group was the party holding copyright on a song that Lessig used in an unarguably fair-use manner. TechDirt is careful not to assume that an actual DMCA takedown notice was issued, on the likelihood that Google's automatic copyright-violation detectors did the deed. "The unintended consequences of asking tool providers [e.g., Google] to judge what is and what is not copyright infringement lead to tremendous problems with companies shooting first and asking questions later. They are silencing speech, on the threat that it might infringe on copyright. This is backwards. We live in a country that is supposed to cherish free speech, not stifle it in case it harms the business model of a company. We live in a country that is supposed to encourage the free expression of ideas — not lock it up and take it down because one company doesn't know how to adapt its business model. We should never be silencing videos because they might infringe on copyright."
