This makes sense. But suppose the author just want to use GPL, not a 
weird license. Or lets suppose that someone else but the author gets the 
GPLd software and asks for a fee of the sources. Without any other 
assumptions (such as this doesnt make sense bc others can give the 
source for free), will this be illegal?

thx
