Open source, community-driven, robust Microsoft To-Do app

Ao is an unofficial, open source, third-party, community driven, free Microsoft To-Do app with a handful of useful features.

What makes this different from the official Microsoft To Do app?
Looks super nice, open source 🚀 But you may get in trouble calling it „Microsoft“ Todo app.
Microsoft? Don't you mean Windows?
Microsoft doing with To-Do apps, what Google did with chat apps. To-Do, Kaizala, One Note and now another?
Mmmm, not better than Wunderlist
