Earlier quoted context omitted.
Do you think Douglass Crockford didn't know that? He was being cheeky and doesn't care. This was also a huge pain point for JSHint and a lot of work went into undoing that by finding a single commit that didn't have the clause iirc.
I looked it up and found this interesting read: https://jshint.com/relicensing-2020/
But, I don't understand why all changes before that (from JS Lint Day 1 until it was forked into JS Hint) aren't subject to that same clause. Why is the Eclipse Foundation not subject to it?
