I still don't understand why there is this feeling that software must absolutely be free.

You don't need to use software that's absolutely free if you don't want to. However, for legal and maintenance reasons software developers and distributors need to be able to deal with clean, absolutely free code. If the Linux Kernel distribution contains non-free code, they face lawsuits and huge maintenance headaches, and lose developers. If the Debian distribution contains non-free code, they lose developers and distributors. If it doesn't matter to you, don't worry about it for your stuff, but let the people who proprietary software harms worry about it for their stuff without griping about the decisions they make.

The Non-GPL Modules are compiled by the Vendors (Nvidia, Promise, and others) who wish to keep the inner workings of their ASICs a secret for business reasons. It is a real shame that some type of API mechanism could not be developed to allow a wrapper type driver to keep GPL Kernel Derived code separate from an interface that should remain proprietary and allow it to do so in such a manner as to satisfy all and allow the device in question to operate.

As far as I know such a wrapper could be written. However, the Linux maintainers have wisely and practically declined to include such a module; if this wrapper were to be in the main kernel, it would be a nightmare. First, including a wrapper would encourage binary drivers, which notoriously include poor or missing support for non-mainstream hardware; for example, NVidia drivers have poor AMD64 support and no PPC support.

Next, this wrapper would have legal implications. Binary drivers in the Linux kernel are debatably a contract violation. The wrapper would potentially make it harder to enforce the GPL.

Also, the kernel developers would increasingly be faced with the choice of making a change to the kernel and dealing with outcry from broken binary drivers, or slowing kernel development. This is a lose-lose choice that kernel developers want to stop confronting; your suggestion would have them deal with it more often.

Proprietary code might have a place in the world, however, that place isn't stashed inside Free Software.

Excellent reply!

This is a much more understandable reason than that of an ideology issue. Shame on me for not doing my due diligence and homework.
I suppose most problems could be worked around as long as the problem is just the one with distribution issues. Unfortunately, I do see the storm brewing about the proprietary modules being developed with GPL Kernel interface code. This is a more complex issue and one that I would hope could be addressed.

I couldn't agree with you more about the lack of support and development for a great number of these devices. The companies I have worked with always seem to get into these ruts and they completely loose interest in the Linux port. This keeps the driver stuck at whatever Kernel level it was built for when the interest left the building. Keep in mind that it is the company interest I am talking about, not the developer's. A great number of us would love to continue our work, if only for the idealist reason that it should be done and be state-of-the-art :) It is painful to hear the complaints and know the shortcomings of the code that is out there while being greatly hindered in any effort to correct the situation. Silly money and profit issues, bah! And you are right about the API issue; the Linux kernel does change often enough in its interfaces as to put a great strain on those who must maintain the API.

Quite true, Proprietary code shouldn't be hiding inside, nor stashed.
