US could learn from Brazilian penalty for hindering fair useBrazil has proposed a broad update to its copyright law (Portuguese) and it contains a surprising idea: penalize anyone who "hinders or impedes" fair use rights or obstructs the use of work that has already fallen into the public domain.
DRM must be defended only when it restricts acts that are "not permitted by law." Since the law in places like Brazil, the US, and many other countries contains fair use or fair dealing provisions, those countries are authorized to allow DRM circumvention for those uses as long as general bypassing is disallowed.
