@porzellanladen More or less, libreboot used to be free and osboot was the nonfree release.

Leah then decided that convenience is more important than freedom and decided to exploit how libreboot was well know to be fully free and renamed osboot to "libreboot"; https://www.gnu.org/software/gnuboot/web/

https://libreboot.org/news/policy.html (of course this policy is intentionally misleading and intentionally contains factually incorrect claims - for example it claims that Intel Wi-Fi cards, which run proprietary software, with digital handcuffs to ensure that it is cryptographically impossible for the user to replace it, is superior for software freedom than the Atheros Wi-Fi cards that don't run proprietary software, but do contain ROM, which appears to not contain malicious circuits, unlike the proprietary software for intel's Wi-Fi card; "No reverse engineering, decompilation, or disassembly of this software is permitted." (don't forget that all hardware must at least contain some ROM for a bootloader - how much ROM is mostly irrelevant as long as it functions properly and doesn't contain malicious circuits)).
