One with more experience with web dev can easily submit the exact opposite comment - web layout and tooling are light years ahead of whatever most recent .NET endeavor.
The web is also already cross-platform, where every platform looks and feels native to itself. This announcement doesn't show off a single native macOS or iOS component. Seeing it's inspired/supported by Xamarin, APIs for look & feel are minimal unless you opt for a platform-specific implementation anyway (e.g., the "common" animations API is a fraction of what one requires for a good experience on iOS).
I'm sure MAUI will be famous in enterprise apps where the latest productivity tool needs to be put together quickly and inflicted on employees for years to come (cough* Teams, Office...).
