There are excellent reasons for Copyright laws.  They encourage creative people to er... um... create.

There is also misuse of Copyright laws.

EFF, the Electronic Frontier Foundation, of which I am a member, takes to task  some of the naughty people who misuse Copyright laws.

EFF says, "Bogus copyright and trademark complaints have threatened all kinds of creative expression on the Internet. EFF's Hall Of Shame collects the worst of the worst."
