AFAIK, the old Redis was BSD licensed. BSD is very permissive, but it doesn't grab the intellectual property to the project: they still belong to the original author (Apache is the only open source license that says your contribution now belong to the project and it is not yours anymore).
That means there is a lot of code belonging to someone not Redis Labs, which Redis Labs should've asked if they can changed the license of the contributor's intellectual property.
This means that the old, BSD-license Redis still exists and Redis Labs should still provide it with the old license. The new, bullshit-licensed Redis should be a fork and, as a fork, have another name.
