And (now that I'm in management I understand this better than I used to) this problem becomes self-reinforcing. If every candidate out there only knows react and doesn't actually know how to do a simple front-end without it, you need to use React because at some point you'll need to hire someone to replace the person doing it. Even when management understands why the design is bad, if that's what the labor market supports it exerts a definite pressure.
