While it is true that Salvatore retired last year, Redis is still FOSS under the BSD license, and it has a new governance team. Redis Labs is in the drivers seat with 3 of the 5 members, including 2 Project Leads. But there are members from Alibaba and AWS https://redis.io/topics/governance

If Redis Labs were to do something stupid with the Redis OSS license, Alibaba and AWS would fork it faster than you can HyperLogLog.

Too help clear up confusion between Redis & Redis Labs, you can read about the various licenses here: https://redislabs.com/legal/licenses/
