This is a letter from FSF regarding the licence - "Responsible AI" License (RAIL). It explained why RAIL is nonfree and unethical.

Summary: Any software license that denies users their freedom is by definition nonfree and unethical, and so-called "Responsible AI" Licenses (RAIL) are no exception. If we want software to help decrease social injustice, we should oppose licenses that restrict how software can be used.
