Apple could change the platform/firmware to break Asahi if they wanted to. They could lock down the hardware to make it nearly impossible to install another OS like they do with iphone.
No Mac in history has been locked down in the way you describe, and there's really no indication that Apple would start now. If they were ever going to, the ARM transition would've been the perfect time to do it, yet they invested engineering resources into adding support for booting non-Apple kernels into their bootloader.
They could of course release a new line of laptops or a firmware update tomorrow which locks down the bootloader and prevents booting non-Apple kernels. But so could Lenovo, Dell, HP, Samsung, Sony, or any other laptop vendor. Or Microsoft, Intel, AMD or Qualcomm could exert their influence, as owners of various parts of the ecosystem, to shift the PC landscape in that direction.
For example, intel and AMD contribute a lot of code and engineering hours to open source projects because they WANT people to be able to run that software on their hardware.
But if you truly do believe that's a good argument, consider Microsoft's position. They wouldn't want you to run non-Windows operating systems and hold considerable power over the Windows PC ecosystem.
Except you pulled this out of thin air. There's more evidence to support the earth will be wiped out by a meteor than their is evidence Apple will lock down their macOS hardware. Your entire argument is predicated on vibes.
If you don’t think a for profit hardware company which also makes operating systems will never think about making it so only their software can run on their hardware, I don’t know what to say to you. They already do this with iphone/ios. It is possible they do with mac/osx. Im not saying it is guaranteed, I am saying it is possible. And I am also saying it is much more possible than a meteor wipes us out in my lifetime. If you disagree with that, fine.
I am pretty sure I will be vindicated by Asahi never being relevant.
They launched this platform with those restrictions, they didn't add them after the fact.
> I am saying it is possible
It's statistically less probable than a meteor wiping life on Earth - so my point stands that that Asahi team would be more concerned with a rogue orbital than it needs to be about Apple locking down the Mac ecosystem.
