Open Source Support reasons. If Linux developers want better MAUI support there is a "Community Repo" to contribute to and help move things further along. The impression is that if things were further along it might get formally "adopted" (by the Dotnet Foundation) for "official" out-of-the-box "support", but it isn't far enough along and doesn't seem to have enough contributors with enough momentum. It currently seems that the Venn Diagram of "Developers that say they want MAUI support for Linux" and "Developers that would contribute to Linux support for MAUI" has too small of an intersection.
Sure, Microsoft could pay more employees to work on it faster, but Linux loves and prefers open source from Linux devs "untainted by Microsoft", right?
