THE MUSIC INDUSTRY PICKED ON THE WRONG MOM: They made her take down a 30-second YouTube video of her kid dancing to a Prince song. She fought it and won. Now she’s out for blood:

Now Lenz is out to teach the music industry a lesson.

What Lenz and her attorneys at the Electronic Frontier Foundation want are for media companies to stop sending take-down notices in a “willy nilly” fashion and to make sure that they have a legitimate claim of copyright violation before acting. They failed do this with Lenz’s video, according to Corynne McSherry, an EFF attorney.

“This video is so clearly noninfringing,” McSherry said. “What we’ve seen is that Universal Music had the view that they could take down Prince content as a matter of principle. But what they were obligated to do was form a good-faith belief that the video was infringing…They may not have formed a good-faith belief at all.”

I’ve noted the vulnerability of these takedown procedures in the past. Glad to see that someone is going after them. Read this, too.
