I may be wrong since this article is from 2018 but it seems like Netfix uses React for everything but their homepage [1]. Facebook uses it's own framework since, well, that framework is React. But their framework isn't some special-purposes framework built for Facebook's purposes either, it's a general purpose framework, used by tons of companies including Netfix. So I don't think many web tech companies are going to find success building their own special-purposes front-end frameworks, like some earlier comments seem to suggest.
