> 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.

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.
