It is a completely naive idea. You export some symbols as
EXPORT_MODULE_GPL(). I write a wrapper which is GPL'd but i don't export
my symbols as EXPORT_MODULE_GPL(), i now can interface to your code from
a proprietry module without breach of license through my wrapper with
very little work on my part. Your probably the same people who run about
using ROT13 as encryption.

That is you decision and you are free to have it, but don't try and
force it on other people by saying if you don't have a system running
100% GPL'd (or compatibly) licensed kernel - we reserve the right to
ignore any bugs you try and inform us about, regardless of whether or
not is is to do with the binary only module. It isn't exactly
encouraging.

Perhaps a less blunt tool could be used to encourage people to release
GPL compatibly licensed code for their previously binary modules? I
think you risk manufacturers withdrawing the support they have given by
saying if they don't release their code we won't support anything to do
with it. Carrots work better than sticks.
