If they truly believed, then they wouldn't bother with a license. Someone who truly doesn't care about copyright wouldn't consider they need a license. The irony would be even more should someone break this license and these believers take them to court. I'm reminded of when the Church of Scientology hadn't bothered with registering the copyrights for many texts, only to rush to court once they leaked. They lost, mostly because they were true believers unable to admit the texts were not divinely inspired.
