I find it surprising that MS hasn't acquired Paint.NET. It's a stellar product, a decent free Photoshop alternative, and miles ahead of whatever MS Paint ever was. It even has .NET in the name, which probably confuses new users into thinking it is owned by MS, so kind of surprised MS hasn't sued over that either.
That said, I'm grateful that Paint.NET has managed to remain independent, as MS might've ruined it.
I do wonder who still uses MS Paint that would find these new features compelling, and why MS keeps adding new features to it. Surely they've done some research that shows people want this? Or is it still developed to justify paying the team that maintains it?
