Asahi Linux Goes GPL Over AI Code Rewrites

Asahi Linux, the volunteer project that ports Linux to Apple Silicon Macs, said Nov. 7 it has begun moving all of its repositories from the permissive MIT license to the GNU General Public License version 2 or later. The project said code was taken from developers' personal forks and, in some cases, rewritten with AI to hide its origin.

Key takeaways

• Asahi says all of its code will be under strong copyleft licenses only going forward, ending its MIT-first approach.
• The project alleges unnamed actors tried to replace it and monetize Linux on Apple Silicon, using unreleased code that was published without credit or "lazily rewritten with LLM assistance."
• Code already released under MIT stays under MIT in at least one key repository, the m1n1 bootloader, so the switch applies going forward there.

Why Asahi Linux is leaving the MIT license

The explanation came in a section of the project's Linux 7.3 progress report, signed by developer James Calligeros. It says the project learned "some time ago" of "multiple attempts to exploit our permissive licensing to hijack our work, with a direct view to replacing the project and aggressively monetising Linux on Apple Silicon."

In "some extreme cases," the report says, in-development feature code was "lifted straight out of our personal forks." It names no person or company and offers no code comparison, so the allegation could not be independently verified.

What changes for m1n1 and other Asahi code

The clearest terms so far are in the m1n1 repository, the bootloader Asahi uses on Apple Silicon. Its README, read by AI Newsway on Nov. 9, says m1n1 was MIT-licensed until version 1.9.9 and that code in those releases remains under MIT. From version 2.0.0, new code is available exclusively under GPL.

The progress report does not explain how past contributors' code will be handled across other repositories. Asahi chose MIT partly so the BSD operating systems could reuse its work, and that bridge is now under strain.

OpenBSD developer Bryan Steele wrote on X that the move came "seemingly without the consent of all prior contributors" and called the rationale "entirely disingenuous and misguided," It's FOSS reported. Asahi's report does not address that criticism.

Can the GPL stop AI code laundering?

Asahi says MIT "explicitly allows" what happened. The license text does permit closed and paid reuse, but it also requires the copyright notice to stay in "all copies or substantial portions," so publishing copied code with no notice is harder to square with its terms.

GPLv2 adds the leverage MIT lacks: a distributed work derived from the code must be licensed as a whole under the GPL, with recipients able to get the source. That only helps if a rewrite counts as a derivative work, a point Asahi's own generative AI policy treats as open, saying questions around LLMs and copyright "remain unsettled."

Copyleft has been a target too. SourceHut, in an August post, cited the chardet library as a case of LLMs being used to rewrite open source software to circumvent copyleft obligations.

A precedent from WINE

Asahi compared its decision to WINE, the Windows compatibility layer, which began under MIT and moved to the LGPL in 2002 to curb proprietary forks.

What's next

Asahi described the switch as the start of a process, and has not published a timeline for each repository. The project already broadly forbids generative AI tooling for material contributions, citing clean-room reverse engineering risks.

FAQ

Can I still use older Asahi code under MIT? For m1n1, yes. Its README says code in releases up to 1.9.9 continues to be available under MIT. Terms for other repositories should be checked individually.

Who does Asahi accuse? No one by name. The report describes the actors only as attempting to replace the project and monetize it.
