> there are just two groups: people who for some reason didn't like React and its way of things, but now found something else they do like (which is good!), but now still have the need to shit on React; the second group likes React and never had serious problems using it.

There is a growing but already big third group of ex-React developers, even ex-React evangelists. You can see them in this thread and I think it is the majority of people talking about React's problems.
