Trying to spring the GPL on people because they dare to try and understand how their wifi card works is not, in my opinion, a reasonable nor appropriate use of copy-left. Copyright is for derived works, not technical knowledge (i.e. specifications) but when you vendors refuse to provide documentation and only code, they force everyone into this weird position of creating a pseudo-derived work if they dare to (or can even be accused of having!) come near the Linux kernel source. If vendors provided a simple PDF everyone would be happier because now anyone can write the driver free and clear to the best of their ability.
