From the BoingBoing article:

In Brazil's version of the law, you can break DRM without breaking the law, provided you're not also committing a copyright violation.

How is it even arguably defensible to make the act of breaking DRM illegal, when (a) the DRM isn't restricting copyrighted material and (b) the person breaking the DRM legally owns the device and data unjustifiably restricted by the DRM?

The US version of Brazil's new law, the Digital Millennium Copyright Act, makes it illegal to break DRM, even if there is no justifiable reason for the DRM to exist. Land of the free?

For those interested in their digital freedom, here is an excellent primer on DRM.
