There is an all too familiar dynamic in conversations about copyright. If you disagree with a proposed solution to a problem, such as the unintended consequences that it can have, then the proponents presume it is because you disagree that there is a problem. I am very familiar with this dynamic when speaking to copyright holders about "DRM" or technological measures as they believe any opponent to the use or legal protection of these measures must be apologists for copyright infringers.
I observed the same dynamic last weekend at the Ontario Linux Fest when discussing some concerns I have with the Affero General Public License (AGPL). The conversation was with Bradley M. Kuhn, one of the people behind the license.
