I don't understand this take. Can you elaborate?

I'm not entirely sure what point you're trying to make, but it seems like the kind of exaggerated intentionally-missing-the-point outrage that conservatives parody leftists for (I say that as a leftist, just to be clear).

Blade Runner has always been about how replicants are people treated as slaves. Rachel having given birth in BR2049 is a big deal not because it means she's finally a person unlike all the other replicant women, but because it means replicants have the potential to control their own destiny, instead of being reliant on humans to make more of them.

The film was extremely explicit about that, to the point of beating you over the head with it. I'm not sure how you could have possibly interpreted it in the way you did, unless you view everything through the lens of "how can I be outraged about this."

EDIT: the comment I responded to originally said something like "Blade Runner 2049? The movie where personhood for women is defined as being capable of giving birth?"
