majority of linux users buy AMD because of drivers alone. avoid broadcom like the plage etc.
asahi linux is weird. theres no good reason to explain its existence other than there are too many people willing to give money to apple for no good reason.
Different people have different needs, preferences & ideological beliefs to you. If you measure the actions of others, based on your viewpoint alone, you will never understand the rest of humanity.
Fucking nobody cares about the gripes I would have with it, and I've even come around to appreciate the fact that Apple sells goods engineered to the desires of people who aren't me (read: the majority): I can't deny the speakers on my Macbook are fucking amazing, and most people would care about that rather than whether something is FOSS.
Sometimes it is even just a practical issue: having as low level control as possible can increase performance in certain aspects, for example in latency related tasks, that can be important in certain applications. This does not make everything else useless, but there are definitely tasks for which I choose an AMD gpu over an NVIDIA gpu (or apple silicon) just because of the open source drivers in linux.
You could also take this to the extreme, as Stallman used to do with his OLPC where he deleted the wifi blob to only use lan because it wasn't free enough. If you have to wait for hardware company's to build free and open drivers and open hardware docs and open firmwares to use linux well im afraid your options are basically some X220 with a Open rom bios reimage.
For now, Apple's arm64 silicon is the most compelling option for anyone that wants to develop on the architecture locally. It's the same way as how i386 was the most compelling option for anyone that wanted to run a free unix at home in 1991. It just does not matter that Apple hasn't done a dump of all their drivers and hardware docs because it is all we have and the hardware is damn good at that too.
i.e making the linux port possible even if not supporting it publicly.
