> how big of a project would it be to create a fully libre (whatever you want to call you it) laptop? But what does it mean by "Libre"? You see, the entire disagreement is about a problem of our definition: How does one define "a hardware system without non-proprietary software"? Ideally, if every single chip in a computer has free hardware design down to the logic gate or HDL level, that would certainly qualify as 100% libre in both hardware and software (if a free operation system is also used). But obviously it's not practical, and it's also out of scope of what the FSF does, it's the Free Software Foundation, and it only cares about software, not hardware. Thus, the FSF defines "Respect Your Freedom" as a hardware system that doesn't require you to execute any nonfree software to use. This sounds like a straightforward definition, right? But for many different types of hardware - essentially 90% of all digital electronics - if you open it up, decap the chips, you'll find a general-purpose microprocessor core executing code in a hard-wired Mask ROM. The chip can be a CPU with embedded microcode, a serial port transceiver, a USB controller, or even a Voltage Regulator Module (just search "DigiVRM"). Sometimes you don't even know it's implemented in this way. Thus, a practical boundary between hardware and software must be drawn. The FSF's argument is basically the following: Consider a blackbox hardware system, such as a chip. Inside the chip, you may find a bunch of logic gates, hardwired to be a finite state machine, or you may find a read-only Mask ROM driving the microprocessor. But it's irrelevant: from the perspective of the software user outside the chip, it doesn't make any difference, it's just an implementation detail in the hardware realm that matters to a hardware engineer, not a software developer. Externally they can even be indistinguishable, if not at the electrical level, at least at the software level. Thus, as long as the logic is not controllable by software, it's not considered as a form of "non-free software" and it gets "Respect Your Freedom" approval. I think there's little to no disagreement at this point, but it gets controversial next. Now, consider two chips, one is a controller and another is its ROM. The FSF argues that, if the ROM is not reprogramable via software even by its vendor after it leaves the factory (if the ROM is 100% read-only, or if the Write function is permanently disabled at hardware level), the controller and its own ROM are collectively considered equivalent to some hard-wired electronic circuitry in the pure hardware realm, using the same argument. Thus it also gets "Respect Your Freedom" approval. However, if the ROM can be reprogrammed (e.g. has an enabled "Write" function) or controlled by software (e.g. uploading a blob by the device driver to the chip), it's considered as a form of non-free software, thus the FSF say it "Does Not Respect Your Freedom". And this is where the disagreement starts. The FSF may insist that a software-controlled firmware is strictly a type of computer program, thus it must be non-free software, meanwhile firmware not controlled by software may as well be a collection of hard-wired logic gates, so it's a "don't care" item for a software user - or at least a form of compromise. The counterargument is that, regardless of whether the firmware control is enabled or disabled, you're ultimately running the same non-free software in both cases (even though, the first case is invisible to software and the second case is visible to software), and it's just a matter of location, either ROM or disk. Since running fixed non-free software is better than running vulnerable non-free software, the "Respect Your Freedom" hardware's "quasi hard-wired" firmware is a waste of time and provides less user freedom. I only described the disagreements, it's up to you to decide. Now, I'm curious to know what would be your definition of "Libre", after learning what I've told you?
