This is false. Per the asahi project, https://asahilinux.org/docs/platform/security/#apples-unspok...

> When documenting the security model, Apple use the example of an XNU kernel developer wishing to test their changes on a second macOS installation. It is apparent however that the platform security model was engineered to allow third party operating systems to coexist with macOS in a way that does not compromise any of Apple's security guarantees for macOS itself. *Rumours circulating that Apple are actively hostile towards efforts such as Asahi, or that their security must be bypassed or jailbroken to run untrusted code are unfounded and false*. In fact, Apple have expended effort and time on _improving_ their security tooling in ways that _only_ improve the execution of non-macOS binaries.

Regarding Framework laptops being "Macs for Linux," Frameworks are fantastic in their own way but they don't come anywhere near the build quality (or battery life) you get with a Mac.

IIRC, when the Asahi project first started, Apple's response was they they didn't care about the project, and would make no efforts to hinder or help them. They also hinted that running an alternate OS was an acceptable use of device.

We will see if they continue that attitude.

Man you randomly reminded me of when magic lantern was completely changing the game with their firmware side load on Canon DSLR’s. Then after a few years Canon decided “nah screw y’all” as they quietly pushed a firmware update that blocked it.
