> which a single side has now altered. No they haven't. "The community" submitted under a BSD licence, they literally gave anyone permission to take their code and relicence it under an alternative. It's not like the BSD version of their code has disappeared. You can still use older versions of Redis that have their changes under BSD. It sounds like submitters should have gone with GPL or AGPL if they wanted it to remain open source, available with the original licence for commercial use, etc.
