Sure, except React easily has the largest community yet (with these types of frameworks) so the argument doesn't really stand for other ones. There has to be really good to reasons to switch to something else completely, and really good reasons not to build on top of React. It's definitely important to look at criticisms, but honestly, these aren't very good ones. It would have been easy to build his library on top of React. EDIT: stronger criticisms in my opinions focus on how hard it can be to get started with an advanced app w/React compared to Ember, which takes a "bundle everything in" approach (the classic lib vs framework debate). Ember is a strong contender especially because it has a great community as well.
