For somebody, like you and many others, it was very important to retain an OSI license. But I feel that in general given that the new license is IMHO good for almost every user, from the POV of what they can do with the code, and that the cloud situation was quite self evident, I believe that with better communication, and immediate developments/merges in the core, to counter balance the license switch, many people would understand the license matter.
We will not win back you as a user, and I respect that. But many, many users that see openness, good features and documentation, the github repository at the center of everything: I believe they will appreciate this, and can decide that Redis is good for them.
