 ```{deprecated} Volto 18
-Using SemanticUI theming for your project or add-on is deprecated from Volto 18 on and will be removed from Plone 7.
-Plone 7 will use another theming approach, based on `@plone/components` and `@plone/theming` packages.
+Semantic UI development and maintenance has sputtered since 2018.
+The Volto Team made the decision to move forward in a sustainable direction.
+Plone 7 will use a different theming approach, based on the [`@plone/components`](https://www.npmjs.com/package/@plone/components)—which in turn is based on [React Aria Components](https://react-spectrum.adobe.com/react-aria/components.html)—and [`@plone/theming`](https://github.com/plone/volto/tree/main/packages/theming) packages.
+Using Semantic UI theming for your project or add-on is deprecated from Volto 18 onward, and will be removed in Plone 7.
