No-comments are better than low-effort, low-quality, unmaintained comments, for sure.

You can imagine a world where all the projects that aren't realistically going to spend the effort on high-quality maintained comments makes the correct choice to skip comments unless absolutely necessary. And where projects that are realistically going to put effort into high-quality, maintained comments, do so.

In this world, comment density would correlate highly with code quality per line of code. Profanity might not, I'm not sure. I do think you'd still find profanity in high-effort, high-quality, maintained comments, but it might indicate lower quality surrounding code, not higher.

And it would still be unclear whether the existence of comments are a cause of higher quality code, or just a proxy for amount of effort and care taken per line of code.
