He made it clear that he won't use any of the code from elsewhere, it's an not-invented-here syndrome on steroids that will result in lots of lost time. :-(
The way I see it is he's just trying to be extremely cautious about legalities. Which should always be fair but especially when you're dealing with a corporation like Apple. It sucks that it hurts collaboration but I find it astonishing that people are trying to blame him for it when all he wants is to protect himself legally.
> then he argues that anyone shipping source in tarballs is noncompliant:
I think he might be referring to the section 2a of GPLv2 (5a of GPLv3) which require keeping track of modifications to the source code. I've never seen this clause being enforced, though. (IANAL)
I also wishes there were some sort of collaboration rather than an outright dismissal.
When people talk about Linux on M1, is that typically in reference to the chipset, or the entire laptop?
The distinction could cause confusion if Asahi Linux (which looks very clean and appears to be attempting to implement support for the laptop and all associated peripherals[1]) and Corellium (which has a bootable implementation on the chipset by the looks of it) have slightly different goals in mind.
The M1 isn't a laptop (and it's not really a chipset either, but sure).
I don't think the differences between the two projects you are trying to highlight are particularly meaningful. The vast majority of the infrastructure and code required is for devices embedded on the soc, not external (like a touchpad).
Asahi looks very clean because it consists of nothing so far.
