Apparently chardet got Claude to rewrite the entire codebase from LGPL to MIT?

https://github.com/chardet/chardet/releases/tag/7.0.0

That is one way to launder GPL code I guess?

Release 7.0.0 · chardet/chardet

Ground-up, MIT-licensed rewrite of chardet. Same package name, same public API — drop-in replacement for chardet 5.x/6.x. Just way faster and more accurate! Highlights: MIT license (previous versi...

@Foxboron lol right, because Claude certainly wasn't trained on GPL code

@scy
US court is leaning towards that LLM generated code is fundamentally not copyrightable.

This is a different problem to the moral issues I have with this.

@Foxboron But does "is not copyrightable" mean that "is not a license violation of its input data"? I highly doubt it.
@scy
A license violation usually implies that there is a copyright violation to begin with.

@Foxboron Yeah but that's what I mean: Just because the end result is not copyrightable, does that automatically mean that it can't be a copyright violation?

Like, changing the format or medium of something is not a copyrightable work.

So, by that logic, if I take a copyrighted MP3 and convert it to AAC and publish that, my AAC is not copyrightable, but it's not a copyright violation to take it and publish it?

That's what I mean.

@scy
I'm not a lawyer so I'm not going to try and debate what is and isn't a copyright violation.

@Foxboron @scy

This will have to go through a court case to settle it probably

But if I look at your source code, then I reproduce some of your source exactly, that's a problem

@joshbressers @scy

Supreme Court has already dismissed such cases.

So we are getting a precedent in US law. Yet to be settled in any high court in the EU though.

@Foxboron @scy

I suspect this is different. That case someone trying to copyright something the AI spit out, not asking if AI can violate a copyright by copying something almost verbatim

Of course I haven't looked to see if the chardet code is mostly a copy, if it's not, then 🤷

@joshbressers @scy

Sure, but we are not really looking at, nor discussing, cases where LLMs spits out something verbatim from another project in this case.

@Foxboron @joshbressers @scy verbatim isn’t the question here, the question is infringement. is the output here substantially derivative of previous versions of chardet to the point that it could be considered infringing? US copyright precedent is a muddled mess and I think this could implicate at least one unresolved circuit split. I don’t know what the answer will be but I know I wouldn’t want to be standing in the blast radius of that decision
