I also want it. I dislike this idea "make it illegal I don't want other people to have the freedom to do something I dislike". Of you don't like unupgradable products, then don't buy them. I like upgradability - apple makes some things like the SSD non-uogradeable without much benefit. But many other parts gain different benefits when you don't try to make everything infinitely upgradable. I really want this non-enshittified macbook alternative!!!! Shut up and take my money.
I don't mind people doing things I dislike (and honestly I'd enjoy changing laptop every month as much as anyone else), I simply don't want people to damage too much the planet where I and my family live.
I think the more important thing is the protocol itself, rather than the specific implementation. As the author notes the current D-bus standards are substandard at best.
