Thanks for the correction. I've made the change in the FAQ to not describe License Zero as an open source license. On its own website, it's very careful not to.
The Lil licence looks promising too.
For completeness: The original License Zero Public License, now dubbed the License Zero Noncommercial Public License (L0-NC), is admittedly _not_ an Open Source license per OSI's definition.
There is now also a draft, alternative public license for L0 projects, The License Zero Reciprocal Public License (L0-R). It's a hair-trigger copyleft-style license, built in much the same way, from a BSD-2-Clause base:

I believe L0-R _is_ an Open Source license, and have submitted to OSI for approval. I also believe it will be as, if not more effective than L0-NC in driving industrial users to purchase private licenses.
