All of this (including the OP) is really a group of artificial
distinctions. All CPUs contain microcode or some programming
equivalent, even going back to the days of gates wired in series. You
may get a Principles of Operation manual that tells you what the
instructions (are supposed to) do in detail, but that's not the same as
seeing the "source" (microcode or wiring) that makes it happen, and it
certainly doesn't allow you to change it at will.
Free Software is about not removing your ability to examine and modify
things you can reasonably be expected to have the skills and equipment
to examine and modify. Most of us don't have the ability to manufacture
our own disk controllers or interrupt controllers. Yet both of those
contain closed-source custom programming, and nobody seems to think
twice about using them in FS environments.
Personally, I think that the reasonable lower limit on "free"
expectations is the ability to burn your own BIOS ROMs if you wish to.
As far as hardware devices that are built with custom programming, I
don't see any distinction between wired logic, immutable ROMs, or
flashable/loadable firmware. Those are all just aspects of how the
manufacturer supports the device (assuming he does). Loadable firmware
may make it simpler for the manufacturer to supply updates and easier
for you to get fixes, but it's no more closed than wired logic is.
In economic terms, what you seem to be asking for is absolute
unbundling, where every manufacturer is limited to making one and only
one thing and relying on multiple competing outside suppliers for other
components with open standards in force at each juncture.
That works best when "commons" are involved, e. g. infrastructure that
can only have one owner, just as the fiber optic cable in a town or the
POTS copper cable. In those cases, whoever granted the monopoly
(usually local government) can classify the resource as a public utility
and require the owner to rent its capacity to anyone who has the price.
This is what happened years back in the U.S. with telephone service and
dial-up ISPs, where the phone companies were told they couldn't refuse
to carry data traffic for independent ISPs at competitive rates.
Unfortunately, the farther down you drill with this, the greater the
negative impact on innovation. If I design a graphic card and I'm not
allowed to bring it to market until I can convince one or more
independent software development companies to do the programming with an
open, documented interface, I may not be able to financially survive the
delay. Theoretically, if the market wants me to document the interface
so that others can compete with me on the firmware, it will punish me if
I don't. But in the meantime, I have the opportunity to make early
profits that will allow me to cover the overhead of doing that later on.
In short, I think you'll find that entusiasm for the Free Software
concept in the marketplace will dwindle severely as you try to take it
further and further down to the level of electrons. Most people will
weigh the inconvenience against the probability that they or anyone
acting on their behalf will ever exploit that freedom.
