We already gave them what they asked for in the DMCA, and now they're back for more. There is no compromise that will suit everyone. I'm not saying abandon copyright, but enforcing it to the degree that they want to is simply not possible without terrifying legislation, because what they want is basically the benefits of copyright without most of the associated limitations (such as having any sort of effort required for big corporations to enforce their copyrights, or for smaller parties to have any option but to capitulate when they are accused).

If we do find a compromise, don't expect the copyright cartel to live with it. They will introduce an even more outrageous bill in five years, and then you'll have to compromise again, and this will repeat until you end up with something much worse than SOPA.
