We at n8n created the Sustainable Use License (https://github.com/n8n-io/n8n/blob/master/packages/cli/LICEN...) and started https://faircode.io/ which could be interesting for you to look at. It is based on the amazing Elastic License 2.0 (https://www.elastic.co/licensing/elastic-license) which you should also check out. Apart from that are there multiple great licenses here: https://polyformproject.org/licenses/

All are obviously not OSI approved.

Hope that is helpful!
