I disagree. Words have meaning. 'Open source' means 'open source' in all contexts.

For comparison, https://doc.rust-lang.org/book/ is an open source book. A PDF with a CC license without a repo of the publishing artifacts is not an open source book. It's just a free book.

The question is not whether it's open source, the question is what it is.
