I find the distinction that dynamically linking GPL is fine but statically linking it is not to be so ridiculous. That's obviously just an implementation detail. The only conceivable difference other than the pointless "technuchalley your program contains GPL code now as part of the file" is that you have to do dynamic linking, which is slightly slower. How does the fact that your work is dynamically linked vs statically linked make any difference to the people writing GPL libraries??
