The issue is there's a license section in the README. There they reiterate that they use BSD 3 clause... and then have something that looks like "but...."
Again, as I read it: they're BSD 3 clause licensed and the README is an expression of their own (ill-expressed) hopes rather than a licensing requirement.... but I could see how some could be confused and indeed... maybe they are, too: and that's what would worry me about this statement.
