I’d forgotten all about BeansBooks, thanks for noting its status. Seems the unmaintained note was added last year and there’s been near zero development for five years. Too bad they didn’t/haven’t released under a real open source license since whatever business (SaaS based on last archived copy of beansbooks.com) they had planned for it evidently didn’t work out.
FWIW I’ve not been following closely but have had an overall positive impression of System76 the last few years, particularly some progress on open firmware for some of their laptops, open hardware design for some of their desktops, Pop!OS seems to be well received, and they employ the lead developer for RedoxOS.
