Which statement are you talking about? First of all it is not clear to
me if proprietary modules need to be GPL or not. If they do, I guess I
have nothing to say. If that is the way developers want it, so be it.

Assuming these need not be GPL, I have a problem with
EXPORT_SYMBOL_GPL and the general trend in the direction of making
proprietary drivers harder on companies. Our drivers use basic
interfaces in the kernel like open, read, write, ioctl, semaphores,
interrupts, timers etc. This is functionality we would expect from any
operating system. We used devfs before and had no problems there. Greg
KH has gone and made the basic sysfs interface, which any generic
driver could use as EXPORT_SYMBOL_GPL. I don't really care, I just
don't use sysfs. The point is that old functionality is being ripped
off and new ones introduced, and their interfaces are not open
anymore. Hence there will be a point where non-GPLed drivers simply
cannot be loaded.

So why beat about the bush? Just make it illegal to load proprietary
drivers, or remove EXPORT_SYMBOL_GPL.
