Reading between the lines. Redis is Hurting, Valkey is making a real difference at pulling the customers away. Elastic and OpenSearch were in similar situation, so Elastic went on to change license back to (more restrictive) Open Source License.
Redis went different route by bringing Redis founder back. I wonder if they go back on their license change next or do they think Redis founder endorsing license change, despite his previous promises of Redis being Open Source forever is enough ? Time will tell.
