Redis has decided to move away from BSD license [redis.com] to dual-license Redis Source Available License (RSALv2) and Server Side Public License (SSPLv1), ignoring many historical failures where other companies tried to move away from open source licenses (ElasticSearch vs OpenSearch, MySQL vs MariaDB, Oracle JDK vs OpenJDK, OpenOffice vs LibreOffice, Terraform vs OpenTofu etc.).
The decision [github.com] has not gone down well within the redis community [ycombinator.com].
