Why is it an antithesis?

HTML UI at the end is just a set of few simple concepts (at least with Sciter):

1. UI is a composition of just two universal components: Element and Node (text, comment, etc).

2. UI is a single rooted tree of such blocks - DOM tree.

3. The tree can be styled by well known CSS means.

4. Events are delivered to particular UI elements using bubbling/sinking event propagation schema.

5. Any DOM Element may have so called behavior assigned to it. The behavior is either native (C/C++/Rust/Go/etc) or script function. All <input> elements are normal DOM elements with corresponding behaviors attached.

I do not see how this simple setup can be an antithesis to anything.

Because Rust is all about efficiency and doing things 'the right way'. HTML is one massive hack at this point and one that wasn't even designed for making desktop GUIs. It's also really slow compared to true GUIs. Remember Firefox OS? Yeah.
