I wanted to hate on this decision but honestly Paint 3D is a much better version of MS Paint. For instance in MS Paint if you write some text in a textbox and then de-select the textbox it's extremely hard to select it again so that you can edit the text. And if you make a square selection and then use the edges of the square to expand your selection, you'll actually stretch the image under it, which I found unintuitive and odd. I think the biggest mistake here was creating a new application called Paint 3D and discontinuing the original one. That's bound to create bad PR. Instead they should have "updated" the original Paint to become Paint 3D, just like they "updated" calc.exe.
