This is coming from a cofounder at github, someone who probably knows precisely what the GPL is for. Whatever the legal merits, building on a GPL3 project's complete test suite and relicensing under MIT is not acting in good faith toward the original authors. I really find it disgusting and it makes me want to avoid gitbutler entirely.

I think you're saying that you don't believe in the freedoms to use the GPL licensed test suite for certain purposes which are explicitly allowed by the GPL.

You don't get to choose a license and then add extra terms to it when you don't feel like it's up to scratch. That's something explicitly not allowed by the GPL license.

Where does the GPL say you have the freedom to relicense code or derivatives under MIT by fiat?

Isn’t having to stay under the GPL a very big part of the GPL license?

The first part of this sentence (where in the GPL) is unreached if the second part of it is unmet (relicense code or derivatives) which I contend it likely is. You're begging the question.

However:

> The output from running a covered work is covered by this License only if the output, given its content, constitutes a covered work

earlier:

> A “covered work” means either the unmodified Program or a work based on the Program.

It's that element that would be difficult to prove "work based on the Program"

Asking an LLM "here's a thing, rewrite it in Rust" is pretty clearly creating either a derivative work or a different form of the same work, just like asking a transpiler would.

There's no evidence that "here's a thing, rewrite it in Rust" is the technique Scott used here.

"here's a test suite, write code in rust that makes that suite pass" is reasonably supported by the article. That would likely not be a derivative work.

		If we assume an u licensed or MIT licensed test suite, an LLM could develop from that and documentation and you’d get something you could license MIT. IMO, IANAL, etc. And we’ll ignore the question of what the fact the LLM has certainly seen the git code during training means. But the test suite would have to stay under the original license. And if you use a GPL test suite as they kernel to develop a program from can you license it non-GPL? I’d question that personally. Same acronyms above apply.
