Because it will always be an uphill battle, where the biggest beneficiary will be Apple. I'm not saying the OSS community should boycott Apple, but maybe let's not help them sell more machines.
I think there are plenty of "good enough" laptops that run Linux just fine, so I'd rather use those than have the relatively "best" hardware, but have to fight it to run the software I want, deal with any incompatibilities, and fear that it might break at any point. Standard Linux on supported hardware has plenty of issues; I can't imagine what the experience is like on completely opaque hardware, as much progress as the Asahi team has made. It's like a reverse Hackintosh project, which has always been a painful experience.
I think that is all personal preference. I'd rather hack around incompatibilities than settle for "good enough" while macOS gets best of class hardware.
