f.lux is not open source, and Apple told it to stop because it tried to distribute itself as an opaque binary rather than something that users could compile themselves.

I don't think this is accurate. The original announcement HN thread includes discussion of the source, which is linked and still online on GitHub: https://news.ycombinator.com/item?id=10550427

The comment you linked discusses the source of a different project, doesn't it?

You're totally right. I remembered that incorrectly and then didn't double check when I saw the link. My mistake!
