I don’t see any of those licenses listed on https://opensource.org/licenses/alphabetical and it took me a bunch of digging in the license-review mailing list archives to find when it was submitted for consideration (most recently anyway, sounds like it was submitted previously too): https://lists.opensource.org/pipermail/license-review_lists....

The consensus on that list is that License Zero violates certain tenets of the Open Source principles, and as such software released under a License Zero license is not open source software. By extension, this means that getting to work full time on License Zero software means that you’re not working full time on open source software.
