JSON non free license

The problem

JSON package is licenced under a MIT license but with an additional infamous clause:

The Software shall be used for Good, not Evil.

This license is considered non-free by Debian, GNU Project, Fedora, Google, Red Hat legal

The author Douglas Crockford is well aware of the harm he's doing but numerous request from different projects and parties could not change his mind.

How can I check

Lintian will help, see #692616.

Check the file for double licensing.

How to solve

I started a petition to ask Crockford to change his license, please sign it: https://www.change.org/petitions/douglas-crockford-remove-the-not-evil-clause-from-your-license-because-it-is-evil-itself
