Asahi Linux drops MIT for GPL after AI was used to copy its code: what it means
Asahi Linux, which brings Linux to Apple Silicon Macs, is moving from the MIT license to GPL after its code was copied and rewritten with AI to hide its origin. Here's what happened and why it matters.
Asahi Linux, the project that lets you run Linux on Apple Silicon Macs, is changing its license from the permissive MIT license to the stricter GPL version 2 or later. The reason is new: the team says people copied its unreleased code, and in some cases used AI tools to rewrite it and hide where it came from. It may be the first major open source project to switch licenses specifically because of AI-assisted “code laundering.” Here’s what happened and why it matters.
What is Asahi Linux?
Asahi Linux is a volunteer project that brings Linux to Macs with Apple’s M-series chips. Apple doesn’t provide documentation for these chips, so the team reverse-engineers the hardware to write drivers. Its latest Linux 7.3 progress report also made M3 support official.
What happened?
In its Linux 7.3 progress report on November 7, 2026, the Asahi team said, according to Runtime Wire, It’s FOSS and Slashdot:
- Some in-development feature code was copied from developers’ personal forks.
- Some copies were published without attribution, meaning no credit to the original authors.
- Other copies were rewritten with LLM (AI) assistance to hide their origin.
- The team said permissive licensing “is no longer viable” because of these attempts to exploit its work.
Asahi did not name the people or organizations it believes were responsible.

MIT vs GPL: what’s the difference?
- MIT license: very permissive. Anyone can use, change and sell the code, even in closed-source products, as long as they keep the copyright notice.
- GPL (v2 or later): “copyleft.” Anyone who distributes a modified version must release their source code under the same license.
Under GPL, it’s much harder to take Asahi’s work, change it, and ship it as a closed product. The team argues the MIT license allowed this kind of copying and offered no protection against bad-faith use.
What is “AI code laundering”?
It’s when someone uses an AI tool to rewrite existing code so it looks different, then presents it as new work. The logic stays the same, but names, structure and comments change, which makes it harder to prove where it came from. This raises tough questions about copyright and credit in the age of AI, similar to the debate over AI companies training on websites, which we covered in our article on the new robots.txt AI training opt-out.
Asahi also bans AI-generated code
Asahi Linux also forbids AI-generated code contributions under its Generative AI Policy. The policy drew criticism from some well-known developers, according to Runtime Wire, which cites a headline mentioning Ruby on Rails creator DHH and Peter Steinberger. Any link between them and the copying allegations is unverified.
Not everyone is happy
The change has drawn criticism from the BSD community. OpenBSD‘s Apple Silicon support relies on Asahi’s m1n1 bootloader, and BSD projects generally prefer permissive licenses. Asahi hasn’t yet explained how it will handle code that outside contributors own, or whether any dual licensing will be offered.
What it means for you
- If you use Asahi Linux on your Mac: nothing changes day to day. Linux itself is already GPL, and you can keep using and updating Asahi as normal.
- If you build on Asahi’s code: check the new license terms. If you distribute changed versions, you’ll need to share your source code.
- If you’re an open source maintainer: this may become a model for other projects worried about AI copying. Watch how the community responds.
- If you use AI coding tools: be careful. Using AI to rewrite someone else’s code doesn’t remove their copyright or your duty to credit them.
Frequently asked questions
Why did Asahi Linux change its license?
The team said unreleased code from developers’ forks was copied without credit, sometimes rewritten with AI to hide its origin. It switched from MIT to GPLv2-or-later to make that kind of reuse harder.
What is the difference between MIT and GPL licenses?
MIT lets anyone reuse code, even in closed products, with credit. GPL requires anyone who distributes a modified version to share its source code under the same license.
Does Asahi Linux allow AI-generated code?
No. Asahi Linux forbids AI-generated code contributions under its Generative AI Policy.
Can I still use Asahi Linux on my Mac?
Yes. The license change affects how the code can be reused and distributed, not whether you can install and use Asahi Linux.
