GNU Project and Free Software Foundation founder Richard Stallman posted a message on the OpenBSD -misc mailing list titled, "real men don't attack straw men", suggesting that some comments he had made were being misrepresented. He noted, "one question particularly relevant for this list is why I don't recommend OpenBSD. It is not about what the system allows. (Any general purpose system allows doing anything at all.) It is about what the system suggests to the user." He went on to note that though he knew of no non-free software included in the base OpenBSD system, there was non-free software distributed via the ports collection, "if a collection of software contains (or suggests installation of) some non-free program, I do not recommend it."
In the email, RMS added that he was unsure whether or not OpenBSD includes any non-free firmware blobs. It was pointed out that OpenBSD is known for being explicity focused on not shipping blobs. As for binary firmware, Reyk Floeter explained, "there is a major difference between binary blobs and firmware images; the blobs are loaded as code into the OS kernel, but the firmware runs directly on the device on crappy embedded micro CPUs." Reyk is the author of the reverse engineered ar5k HAL OpenBSD uses to support the Atheros wireless chipset, which was recently adopted by the Linux-based MadWifi project in their ath5k driver. Reyk added, "I'm clearly against binary blobs in the kernel, and in contrast to most of the GNU/Linux dudes I _did_ some against it by writing ar5k, instead of pointing into the wrong direction. This open firmware discussion is just a joke to make the relevant discussion, binary blobs in the OS kernel, irrelevant." Marco Peereboom added, "OpenBSD is by far the most free OS in the landscape. Everything that ships with it is free or else it won't be distributed with it. There is not a single open source OS out there that is more careful than OpenBSD on licensing, copyrights and frivolous patents."
