The rewrite from Xamarin.Forms into MAUI, has given a bad taste to many in the community, and kudos to Avalonia to make it happen on GNU/Linux.

By the way on macOS MAUI uses Catalyst as backend, not native macOS APIs.

Also it is kind of interesting that Miguel de Icaza, nowadays completely switched into Swift ecosystem, and is the responsible for making game development on iPad with Godot a reality. Or porting old .NET ideas of his into Swift.
