Disclosure: I work for AWS, but I am not speaking for the company.

The Redis case study is a nuanced one. The core Redis code is BSD-3 licensed, and adopted a lightweight community governance model in June of 2020 [1]. This model includes a core team of individuals, and seeks to empower individuals who demonstrate a long-term commitment to Redis as a community-driven project.

The core team is now made up of people who currently work for Redis Labs, AWS, and Alibaba [2].

From my perspective, on the core BSD-3 licensed Redis code, it is in all stakeholders interest to collaborate on the "upstream." There's one Redis, and it is the version that is produced by the Redis development community, and Redis Labs acts as the primary sponsor and steward of the project.

Fair, I am using Redis as an example here, because I know more about (the technical side of) their product than some of the others. I think similar considerations apply to Mongo, Elastic and the others.
