You haven't used vue 2 or svelte then. Modern React is big and opinionated (just like Angular). When people talk about react they are not just talking about a state management library anymore
Vue and Svelte are just as complex as React, I'd argue Vue often ends up being even more complex than react even though the barrier to entry is a bit lower for novices. If you disagree, I encourage you to link to a mature project on github built with svelte or vue that you regard as an example of simplicity.
