ianal but does it even work like that? Is there any specific reason to think it does? I don't believe you really get credit for purity and fairness vibes in the legal system. Same goes for the idea that code where it is ambiguous whether it is AI output could be considered public domain, seems kind of implausible, is there actually any reason to think the law works that way? If it did, then any copyrighted work not accompanied by proof of human authorship would be at risk, uncharacteristic for a system focused on giving big copyright holders what they want without trouble.
I'm mostly just playing along with your thought experiment. As I said, we know that projects are already accepting LLM code into projects that are nominally copyleft.
There is no way, leaks happen, big tech companies have massive influence, a situation where their code falls into the public domain as soon as the public gets their hands on it just isn't realistic.
If that is the case, is chardet 7.0.0 a derivative work of chardet, or is it a public domain LLM work? The whole LLM project is fraught with questions like these, but it seems that the vendors at least are counting on not copying leaked software and instead copying open source code that is publicly hosted.
Why is it okay to strip copyright from open source works but not from leaked closed source works?
We know that Disney is suing to protect its works - if it is true that LLM outputs are transformative, they should lose, as should any vendor whose leaked code was "transformed" by an LLM.
