I haven’t heard of MAUI. Looks like XML UI development, which some may or may not like. Regardless, I think multiplatform frameworks are great for developers who are willing to use non-native tools to build a uniform experience that everyone can use while minimizing code duplication, as long as the look and feel seem native feeling to the end users. If someone wants to build one, I’m all for it. More client implementations mean more choices for end users, it’s great for market competition and everyone wins. I think Plebstr is multiplatform but not sure what their stack is, they’re not open source.
I started building native iOS and Android for a new app because I wanted to have experience building purely native apps (I’m usually a backend developer)
