Had tweeted about this sometime back. Found a component which was open source earlier and then removed and only minfied JS was provided. Give the JS to Claude and get the original component back. It even gave good class names to the component and function names.
Actually this opens up a bigger question. What if I like an open source project but don't like its license. I can just prompt AI by giving it the open source code and ask it to rewrite it or write in some other language. Have to look up the rules if this is allowed or will be considered copying and how will a judge prove?
Almost likely you would be found guilty because the intent matters. It is easy to check that the generated code is much similar to the original code, and you surely had a reason to bypass the original license. The exact legal reasoning would vary but any reasonable laywer would recommend you to do not.
In the historic Google v. Oracle suit, the only actual code that was claimed to be copied was a trivial `rangeCheck` function, but Google's intent and other circumstances like the identical code structure and documentation made it much more complicated, and the final decision completely bypassed the copyrightability of APIs possibly for this reason.
