They don't because since React set the bar, any new framework that didn't solve the problem VDOM did in some way, was dead on arrival.
If Svelte way is better at minimizing and batching DOM updates, they should probably argue and show that, not misrepresent what VDOM does (while blaming strawmanning on others no less).

Most frameworks before and after React were solving that problem one way or another.
The reason React won was that V = f(S) turned out to be most user-friendly solution. VDOM is exactly what Rich is saying: a means to efficiently implement V = f(S)
Vue/MobX are another, better iteration on the same idea. Svelte, arguably, is even better iteration.
