Do you have a link to information about this decision? I haven't heard
about it from anybody other than yourself, and since such a decision would
have quite severe consequences, I would be surprised that I didn't read
about it anywhere else. "Would be" instead of "am" because until you supply
evidence, I think you are wrong.

I know about the taint message, as I see it whenever I look at the dmesg
output (The OpenAFS kernel module is IBM Public License != GPL, and the
nVidia/ATI drivers are also != GPL), but it is simply information, and
does not imply any restrcitions.

If you are so concerned about this, you can take the kernel and modify it
to still allow non-GPL USB kernel modules. Besides, if you dig a little
deeper before starting to whine, you would find out that the "problem"
probably won't exist when this is implemented.

I decided to look it up myself.

>From Documentation/feature-removal-schedule.txt:

What:   USB driver API moves to EXPORT_SYMBOL_GPL
When:   February 2008
Files:  include/linux/usb.h, drivers/usb/core/driver.c
Why:    The USB subsystem has changed a lot over time, and it has been
        possible to create userspace USB drivers using usbfs/libusb/gadgetfs
        that operate as fast as the USB bus allows.  Because of this, the USB
        subsystem will not be allowing closed source kernel drivers to
        register with it, after this grace period is over.  If anyone needs
        any help in converting their closed source drivers over to use the
        userspace filesystems, please contact the
        linux-usb-devel@xxxxxxxxxxxxxxxxxxxxx mailing list, and the developers
        there will be glad to help you out.
Who:    Greg Kroah-Hartman <gregkh@xxxxxxx>

As you can see, the non-GPL USB drivers will move to userspace instead of
kernelspace. This is thus a technical decision that hopefully will not be
noticed by end users. All your fears should instantaneously evaporate,
since they were all based on flawed assumptions.

I understand perfectly why the kernel developers did this. If there is no
disadvantage of running the drivers in userspace, why insist on keeping
them in the kernel? Closed binary kernel modules are a problem, since they
make debugging much harder or impossible. They should thus be kept out of
the kernel if possible, since it reduces the number of potential
undebuggable kernel systems.
