After watching the video, and regardless of License debates I feel like this is a spiritual child of Blender and Sketchup. I assume it's done intentionally since the person in the video (I think a developer of the soft ?) directly refers to Blender and anyone who has used it will instantly recognize some key pieces of UI that are its (sometimes infamous) hallmarks.
The UI / UX looks like Blender's, but stripped down. Not a bad thing in on itself, it's like if all the things but the 3D modelling workspaces were removed from Blender. Also it looks like the visual feedback is interesting, with gizmos in each operation.
However, all the modeling operations seem to be destructive which is one of the things some people complain about in the traditional 3D modelling workflow in Blender, that's slowly but surely being resolved with Geometry Nodes. Also, it seems it takes the Sketchup approach in terms of topology, that is to say totally abstract the user from it. All the faces are N-gons and it always looks good in the viewport. I think while for some modelling workflows it's not a problem, it's really not ideal in all situations. Namely for animation, for exporting to other softwares and subdivision workflow it's a nightmare.
All in all I really don't see myself paying $25 for it when Blender has all the features I saw in the video and more (minus some of the gizmos), and is truly FOSS.
However seeing the current discussion on Application Templates in Blender to restrict UI to specific workflows, I can see this being used by non-power users to achieve specific modelling goals, like early stage design of hard surface models.
