The moment it went with Catalyst on macOS and forgot Linux exists entirely it was dead on arrival. It's Xamarin Forms but worse. Well done Microsoft slow clap.
Not even the new VS4MAC UI uses MAUI, they used their own bindings.
I understand holding out hope for year of the Linux desktop, but ignoring Linux has never really hurt anybody, has it?
Electron, Qt, Anything Java, Avalonia, wxWidgets, all the native webview wrappers, etc. All have Linux support.
