I don't think that's a necessary consequence. React is free, a sort-of recruitment loss-leader for Meta. Imo you can get to a moral zero on this pretty easily despite still using React, by supporting out-of-Meta React OSS and using your platforms to denounces Meta's carelessness.
On the other hand: Companies pay for Microsoft's offerings and they support the Israeli military in their genocidal campaign in Gaza, I think getting to a moral zero on that is significantly harder.
