Copying is a harsh word IMO. Vue has been liberal and open in quoting prior art, particularly from the React ecosystem. For example vuex[0] docs, actually quotes Dan Abramov regarding flux implementations for state management.

Programming and open source is a massive ecosystem of making use of prior art and incorporating diverse ideas to make alternative, better, or more robust abstractions. That's the whole beauty of it. Very few things are entirely new.
