This is either brilliant or scary:
Anthropic accidentally leaked the TS source code of Claude Code (which is closed source). Repos sharing the source are taken down with DMCA.
BUT this repo rewrote the code using Python, and so it violates no copyright & cannot be taken down!
Because it is sufficiently different and if github gives in then they will alienate a lot of developers.
If anthropic has a problem with it they can bring it to court.
Again, that's not how the DMCA works.
Github doesn't get a choice, and the claimant going to court happens after the uploader files a counter-claim including their details. (github doesn't get a choice in that either)
It's fucked up, but that's what the law is.
