I don't, however, I don't claim to live by the same free vs non-free

    rules, I use what works for me.
Since these principles are not yours, you could very well have

misunderstood them.  So you are criticizing me for something that

neither you nor I says is wrong.  What's the point?
    There is a free copier of hardware: you, me, or anyone with a certian

    amount of skill, and the required wires and other parts.  This is how

    the entire home PC business started, the whole homebrew market. 
That's true for some kinds of hardware, to a limited extemt.  But

building copies by hand is very different from having a copier that

will copy them automatically.  I don't consider them ethically the

same.
    Hardware has source code.  Virtually every major piece of a computer is

    written and modelled in Verilog or VHDL these days, which is bytes on a

    disk, in ASCII characters, which sounds pretty much like code. 
"Source code" and "plans" are not the same thing.  What makes software

source code special is that a program can compile it into a working

executable.  To turn the plans for a chip into a working chip, you need

a fab line that costs millions of dollars.
Some day, if we all have personal fabs that can make chips, and robots

that can assemble them into computers, the situation for chips will be

much more like the situation for software today.  In that situation it

might very well be important to campaign agains non-free chips and

non-free computers.  But in today's situation there is no reason

to do so.
    Technology can allow for "free" hardware, just as well as it can for

    hardware.  If there is "open-source" and "free" hardware designs and

    code, anyone with a FPGA, or availability of various other technologies

    can take this hardware design, make changes, and make it better.
You are talking about programs for FPGAs.  Those are software, and if

they run on platforms where it is normal to install different

software, then they should be free.
But I think the FPGAs in products are more like the possible computer

in my microwave oven: nobody installs software in them, so they might

as well be circuits.
