Is it really the case that Facebook marketed heavily React? Why? What do they gain from it? Real question, or not like react was an entry point to their API?
It was fairly obvious when it was an up and coming thing. They sent out engineers to talk about it, you had these articles popping up about it more or less out of nowhere, etc. If you weren't there (which I'm guessing you're not, otherwise why would you ask), it is hard to imagine. Perhaps it makes more sense when you consider how normal "advertorials" are now.
