On the surface of it, it looks like literally no one wins. Redis Labs are going to lose a large amount of labour they've been getting for free. This seems like biting the hand that feeds it.

Users lose out on the fruits of that labour, harming bug fixes, feature development etc., as well as now having to consult with legal experts and the like to ensure there is no chance the fall afoul of the new license (you need to be really careful with the wording and the way it might be interpreted, not just how you interpret it or how Redis Lab's blog post suggests it is), and any time and hassles spent switching.

The people providing that labour now have the hassles and expense of forking, setting up governance, legal stuff etc, when they could have been just getting on with things.
