Sure, it's not OSI-OSS, but what does that mean for the world, in practical terms? One practical consequence: Linux distributions will drop the new Redis, and ship its OSS fork or an alternative protocol-compatible cache. Or perhaps continue with the pre-license-change version for a while, which is a kind of fork. What was the relatively simple "apt install redis" will now be "apt install freeredis" or "apt install awesome-cache" or "apt install redis73". So you will have churn. I don't have an idea how many installations are via the official docker image; they won't change, but even there now you have a legal risk, however tiny: will Redis Inc. come after us for our usage? Legal departments are allergic to risk: witness their aversion to GPL variants, especially GPLv3 and AGPL. So perhaps there will be pressure to avoid Redis, again causing churn.
