and then I'd show him a news broadcast from last week, where the president of the United States of America literally said "War is peace".

from TFA:

> That looks complicated, but remember how we built it: we looked at the hints and selected one option at a time. Now, if this is a log type we’ll use often, we are going to start to be able to write out that incantation without even looking at the hints. It’s both discoverable and efficient.

If the clean room re-write was done entirely by Claude, then the result cannot be copyright in the USA, and thus there is no license at all.

And if he was in fact more involved (which he appears to deny) that it's a bit weak to say that someone with huge familiarity with chardet could choose to reimplement chardet without the result being derivative.

But more than 90% of all the written-composed music from western Europe and North America (at minimum) over the last several centuries does not use integer pitch ratios.

If Blanchard is claiming not to have been substantively involved in the creation of the new implementation of chardet (i.e. "Claude did it"), then the new implementation is machine generated, and in the USA cannot be copyright and thus cannot be licensed.

If he is claiming to have been somehow substantively "enough" involved to make the code copyrightable, then his own familiarity with the previous LGPL implementation makes the new one almost certainly a derivative of the original.
