100% agreed. it upsets me when i see companies like framework advertising themselves front and centre as Linux-first, yet won't sponsor a coreboot port. starlabs, system76 and novacustom actually walk the walk
Framework plans to eventually support coreboot, as far as I am aware. (Or open source the current one they purchased).
It just wasn't the main priority.
They focused on making a repairable laptops ecosystem first.
Switching to different firmware later isn't ruled out.
Starlabs is at least as repairable as framework, older, and coreboot.
they originally announced their intention to open the firmware 4 years ago
