I think you are very much over-valuing how much companies care about FOSS in production. Unless the intent is to be able to fork and support it in house (which is almost always a bad idea), it isn't really a concern. What matters is the license. And... spend enough time having to all but physically smack people on the nose for even thinking about the (corporate) cancer that is LGPL and you get different thoughts about the importance of FOSS in Production.
I would definitely be wary of a license change. I have personally not checked what the new Redis license is. But if it is still favorable but also looks like something they can profit off of? I would probably put it in their favor. Because that suggests they are done being obnoxious. Contrast that with something like Hashicorp's bullshit where a LOT of companies don't even bother to pretend to be diplomatic when discussing how much chaos they caused.
