It’s true that frameworks e.g. Django, Ember, and Phoenix may limit flexibility and scalability in the long-term, but forgoing a framework up-front is, like microservices, a premature optimization; you might become successful enough to need to break things apart, but if you do that too early, it might limit your ability to become successful in the first place. Put 10 React developers in a room, and you will hear ~10 opinions on how to handle routing, state management, tooling, testing, file structure, etc. Startups don’t always have time for that nonsense. True, you may need to work harder to find decent Ember devs vs. decent React devs (and pay the Ember devs higher salaries when you do find them). But they are more likely to skip the bike-shedding, hit the ground running, be productive much earlier, and sustain higher output than their React counterparts.
