My person always rejected the use of common "free"-licences, being total improper for Dhamma, beginning already with "right to consume", indicating wrong view, and that common principles agree and tolerate harmful and improper use.
Thought some might be interested in discussions about the topic, here for example:
Possibility for "good purpose only" contributions to DW? (a "holly", "generosity only" forge) (post are mostly censured and edited)
Whether one put Dhamma or "good" under common creatives, open source or GNU, all this is actually an approve to use it not only for harmless but also harmful deeds and undertakings.
A "good" juristic sample is surely
Good, not Evil This world is caught by
Mara and "nobody" likes to give up things for a better: greed.
