I think where tptacek is right, though, is that if we're going to hold this position without hypocrisy, then we need to respect copyright as long as it exists. He's right that many of us have not done that; it's been very common to violate copyright for mere entertainment. If we want the licenses of our own work to be respected, then we need to extend that respect to others as well, regardless of the size of the copyright holder.
