The issue ‘One persistent myth is the special role of "linking" in propagating "derived work" copyright status’ has nothing to do with GPL.
If you use any 3P library it’s a derived dependency by law. Is that what you are arguing? It’s settled law at this point.
MS lets you link against their DLLs but only on their platform. You might pay for a special library, but you have to pay them money for programs that link against it (actually does anybody do that any more?). GPL code is no different in any way except instead of paying the FSF cash or buying a Windows OS you agree to provide the user the freedom to change the code.
