I must admit I'm somewhat sympathetic to Marius' aims, if not convinced about the actual details.
Ideally, I would like to craft a dual license that says, in legalese, "if you don't pay, reciprocate; if you pay, you don't have to reciprocate". QED. However like Marius I find the GPL and other open source licenses inadequate to express this, since most if not all allow certain situations to avoid reciprocation e.g. internal use, web services. I should think GPL and friends were never designed to be the "bad cop" part of a "good cop, bad cop" dual-licensing scheme to get priopetary users to pay. Practically, the GPL does cover most of what I want and ultimately not being Microsoft or an army-of-lawyers-employing company, there's not much I can do to enforce it except the moral authority of being the copyright owner. So it looks like it shall be GPL + some simple BSD-like priopetary license.
