alt Hacker NewsI see it differently. I look at it as if I had written this code myself, using this same approach. Look at the docs, look at the tests, look at the source, implement something that is interactively compatible but a very different approach.
For example, this is exactly what I did when I tried to get SSH commit signing working properly in GitButler:

You can see in the post that I dug through the C source to figure out how it was canonically done and then implemented something that accomplished the same thing in Rust but without copying source code.
There are some similarities between the Grit Rust source and the Git source, but it's mostly around time/formatting type things or byte offset type things needed to make packfile parsing and whatnot work, but as far as I can tell, there is no straightforward copying of code. The approach needed to make this a reentrant, memory safe, library driven codebase is so different that copying is generally not useful. But nobody can _guess_ how packfiles or reftable binary formats are specified, since they're not really documented. I'm aware of this because I'm pretty sure I _personally_ am one of the only ones who has ever attempted to document the packfile binary format: https://schacon.github.io/gitbook/7_the_packfile.html
You have to read the source. Which means that libgit2 and Gitoxide and every other Git reimplementation is also "license-washing" per this definition because they also had to reference the Git source to see what the technical specification is.
If you find any code in Grit that is clearly line-for-line copied, please point it out and I will replace it. But the Git source is the Git specification and every reimplementation, LLM or not, is forced to use this approach to build anything compatible.

Why is it everyone else’s job to figure out if you’re compliant with the license? That’s your responsibility.

This makes no sense:
1. A court might agree with you if a human read the sources, then wrote a new implementation. Doesn't apply to trade secrets (i.e. cleanroom implementations), but certainly for copyright.
2. A court is not going to agree that passing the original sources through a machine means you own the results!
I mean, that's what it comes down to - as far as the courts are concerned, passing copyright stuff through a machine results in the output retaining the original copyright. Passing copyright material through a person is not so clear cut.
You're a thief, and a slopper. Wow.

I could look at a C to Zig compiler in the same way: I read some C code, write the equivalent Zig code, repeat.
The compiler could also do some circumlocutions in order to provide an apparently different approach.

Please hunt for specific lines to disprove your bold claim.

Assuming the current claims here, that would just be license washing with volunteer assistance.
Yet, you didn't write the code yourself.
On Gitoxide: Given that the author read the docs and source code [0], and literally copied files over from the git source [1], it also is license-washing. At least libgit2 is GPLv2 with a linking exception. I don't think people would have much to say if these projects honored the original projects' intents and kept a copyleft GPL license. But they don't.

This is obvious given how different Rust is from most languages. So are licenses pointless as a concept now, because anyone can argue their Rust implementation of a GPL (or whatever) project is meaningfully different? Nice loophole there.
Stripping away the GPL in favor of MIT/ASL2.0 seems to be the trend for rust projects (see uutils, etc). I'm really glad that we can make it easier for large companies to extract value from community labor and, in general, not contribute much of anything back.
