"sources of truth" usually refers to data. Having some designated separation of presentation and data is usually understood as a good thing. I get that having them located in strongly separated locations increases workflow friction, but that isn't how Vue does things, and the rest of the problems you're talking about are present in any system where presentation and data have some kind of separation convention. I'm also not convinced there where React is used to collapse the difference between the two it's actually solving problems rather than switching to a different set of problems, but then again I suppose every engineer has the right to pick which set of problems they prefer to wrestle with.
