    > So maybe what Redis should have done is not to pull the existing rug, so to speak, but to leave it be and lay next to it a new, better rug and offer the users sitting on the old rug to move over, if they find the new features of the new rug outweigh the drawbacks of a new license.

Can you provide more specifics about your idea? It sounds like Redis would need to maintain two version. Can your ideas be implemented with the same cost structure? I doubt it.

I'm referring to my own comment, but I think they are suggesting something close to this[1].

Yes, pretty much. I think it would also be good (but admittedly risky) to accept third-party contributions (even new features) to the old version. In other words, instead of trying to force people to use a new license they could have tried to entice them.
