> During the past year (2020), Ignacio Etcheverry worked on significantly improving C# support and its integration in Godot, adding support for Android, HTML5 and iOS, as well as popular third party IDEs. This was financed thanks to a generous donation from Microsoft.

Nice find, thanks! Turns out Godot reached to Miguel de Icaza for a few grants from Microsoft for C# integration around 2017-2020. Coincidentally, I can't find any mention of Microsoft grants for Godot after de Icaza left MS. I guess we found who used to care for Godot at MS.
