Yeah, but fiatjaf is saying that Tom Dale (one of the creators of Ember.js) believes that React is better than Ember in every scenario, not the opposite. That's the part that doesn't make sense.
Yeah, but the point is that he's conjecturing and doesn't provide any source. If anything, I'd imagine Tom Dale believes that Ember is better than React in some, if not all, ways given that he's... one of the co-founders.
fiatjaf is literally saying[0]:
> React cane out after Ember, and conquered the hearts of many many JS developers. Why couldn't Tom Dale be one of them?
And it's fine to wonder that, but he states it in the original comment as if it's a definite thing without providing a source.
If Dale Said it otherwise, im sorry. Its all about opinions Here :-/
