That's a misrepresentation. The commits in question were confined to
the new, not previously existing, port to arm64 windows. And then what
happened next? The real issues were identified and the correct
solutions were inserted. Who was harmed?

If you want to stop using SBCL because of "AI", you have my
endorsement. Because I myself too am using LLMs (the free ones). Not
to edit files in the vibe fashion, but as a smarter google.

The ship has sailed, you won't be able to find things that pass your
purity tests.
