Subject: Point of gpl-only modules (flame)

I know I'll be getting hell for this, I must be a masochist.

Anyway, I've been trying to figure out what purpose the gpl-only code
serves.
What good comes out of disabling people from probing modules that do not
have a gpl-compatible license?
Of cause, I would love to see more hardware manufactures release either
full specs, or GPL'd drivers, and I'm sure it will happen, in time.
But until then, why are people wasting time writing code to inhibit
those who do not agree with them on licensing?

It seems pretty childish to try and force some license on people,
imagine trying to install firefox on Windows Vista, an error-dialog box
appears:
"This application has been denied access to the Windows API as its
license are compatible with the Microsoft Philosophy" ?

Now, i don't want to waste clock cycles on executing code that serves no
purpose but restraining me from using my $1500 gfx card as intended, so
will me removing that crap from the source result in somebody trying to
obfuscate it to a point where neither of us know what is what?

Also, how about a list of PROS, explain to me whats so cool about it?

People who do binary-only drivers have a much better chance of not
doing a derivative work when they only use non-EXPORT_GPL exports, and
as a result not being in the wrong legally.

find /lib/modules/`uname -r` -iname '*.ko' | wc -l:

2021

Proprietary modules that I can think of:

5 to 10

It's not even 1/2 a !#$ percent. (Though knowing that many modules are for
not-so-common hw.)

Not a kernel problem.

(That said, MS would probably face yet another antitrust charge if it did that.
Or better yet, people would just thankfully stop using it.)

Perhaps you intended to buy a game console instead?

That said, no one is restraining you. You can edit the kernel source
and rip out all the GPL checks. On top, it's not like the ati or
nvidia blob-ola would not load in today's kernel.

Oh yeah, my kernel (unpatched, btw) really tries to stop me hard
from loading it.

Jimmy, a simple script can generate a link object that
will resolve any kernel symbols for your module without
any "export symbol" stuff at all. This was previously
demonstrated to the enraged few who considered it
immoral. Nevertheless, it's just as moral as bypassing
RIAA copy protection.

Just don't expect the kernel developers to authorize
its use, or show you how to do it!

Well of course you can be totally up-front and public about it. That,
after all, is the point of GPL.

Who is disabling anything?

The kernel gets marked as tainted when you load proprietary modules
because with no source code available there is no way to determine what
kind of badness the code may have done to break the kernel. Bug reports
from tainted kernels are generally given fairly little weight.
