permissive licenses dont bother me. im aware of the argument against them, the gpl is a reasonable response to that, but the gpl is a tedious license (for hobbyists) in many ways.
im not anti-gpl, gpl is probably necessary
for many things. for important projects especially. i use #cc0
for most of my code personally.
for me, a vibrant public domain is something we should all be working towards. stallmans rhetoric about the public domain is acceptable, but cc0 lets us do something right now. so even if gpl is needed for some things (the kernel, the gnu project) i still dont think it is necessary for everything. its a strategic response to monopolies. even the fsf makes exceptions (the difference is where the line is drawn.)
