But if you circumvent copy protection for the purpose of sharing copyrighted works publicly then you were already doing something illegal before section 1201. All section 1201 does is also make it illegal to circumvent copy protection even if you don't do anything else illegal under copyright law, like keep copies of movies you bought privately in a digital collection that you can back up, or using software that you payed for when you aren't connected to the internet. If we think circumventing copy protection for the purposes of copyright infringement is extra bad, why not just add additional penalties to additional copyright infringement?
