Disclaimer: I am not a lawyer, this is not legal advice.

In theory, one would not be able to offer a combined program under other licenses (in particular, RSALv2 and SSPLv1), as those licenses have conflicts with GPL obligations.

Direct contributions to the Redis project avoid this issue via a separate Contributor License Agreement. It would only mean that Redis developers could not unilaterally copy code from Valkey.

I'm not saying that the Valkey community should do this. Personally, I think it's better off as a BSD-3 licensed project, with the community fulfilling the promise made by others that it would always be that way.
