I am not talking about the hardware. If I want to change the hardware I have to make something myself, or more realistically, replace it.
Don't mix the actuall hardware with the software that makes it work.

That is exactly my point.

If it cannot be changed without replacing the chip or hardware, then it is hardware. Stallman said this himself in many of the various speaches he'd made.
But if it can be changed by flashing the chip with new software/firmware/biios, then we should have the sourcecode and freedom to do what we want with it.

Yes. BIOS is also firmware. :-)=

That's where the difference of opinion is.
I have the same opinion on this as Stallman and FSF have. If it can be changed/replaced by using software (i.e. flashing the hardware), we should have the sourcecode with the four freedoms.
If I don't need to install a non-free package to make the device work, then I don't have a problem with it. I mean, I use computers with non-free BIOS. I don't have to install something to make the BIOS work with my operating system.
> In economic terms, what you seem to be asking for is absolute
No. I just want to be able to change the software that is needed to make the hardware work. How they solve that is not my concern. They can release free drivers and firmware, or they can document how it works, and have the community make the drivers. I don't remember who or where, but there exist a community that is willing to make the drivers. All they need is the documentation on how the device works, and they will make drivers and if needed, firmware.

They already make only one thing: The hardware. The firmware and drivers only interact with the hardware to make it do what we want it to do.

Again you are confusing hardware with software. I am not talking about having the hardware manufacturrs to publish blueprints on their hardware, only document how it works. There's a difference.

Which is not at all what I'm discussing. You can publish the driver/firmware as Free Software, and the Free Software community will happily buy your hardware just like any other hardware. They migth even prefer and recommend it.

I have no problem with that. That only means that those of us who insist on Free drivers and firmware will be looking for other hardware that have free drivers, untill the time comes that you publish free drivers/firmware.

I am not most people. ;-)=
