Apple really has no business getting in the way of this - it would just hurt them on a general purpose computing platform like Macs are.

It's quite likely this isn't specifically for Asahi Linux. Some BSDs are also working on booting on this, which might permit Apple some flexibility in future products using Apple Silicon (Apple's Time Capsules, say, have apparently run NetBSD as opposed to an iOS derivative).

Apple would also likely be welcoming to Windows for Arm running natively on macOS. While Apple wouldn't probably be justified in coughing up the costs for writing complicated drivers - notably graphics drivers - to make Windows run on it, they have incentives to make someone else doing that as easy as possible. Macs running Windows just sells them some percentage more Macs. As does Macs running Linux/BSD most likely, but that percentage is smaller.
