Alex writes, "This is a very good example of copyright abuse. The official Blender Foundation copy of Sintel on Youtube is currently blocked because Sony apparently claimed copyright over it. This is particularly distressing because Sintel is one of the precious few open-source movies in existence. Made with open-source tools, licensed under Creative Commons Attribution 3.0, with the source files from the movie free to download, Sintel represents the diametric opposite of this type of ownership. "
While it's probably a mistake, because this is so brain-meltingly obviously wrong, it's also a very stark example of how sloppy, over-broad, and consequence-free enforcement of copyright can damage culture.
