While the tone of the entire post is unsettling, it does say that the core server is still BSD licensed.
>Redis’ permissive BSD open source license allows them to do so legally, but this must be changed.
Doesn't seem like having Redis core contain enough useful functionality and staying BSD lines up with their vision.
>But now, for the first time, GPL could be interesting again because of the cloud vendors. Because with BSD, cloud vendors are able to extract a lot of value from an open-source project, to the point of making it very hard for the project’s initial creators to make a business out of it. Let’s call it the “AWS problem.” The AWS problem, technically, could be enough in some way to create problems for the whole open-source ecosystem. Now people know that if they start an open-source project and put a lot of effort into it, they could be marginalized by AWS. That could mean that GPL would return again as the primary license for open-source software in the future.
Do you want forks? Because this is how you get forks.
