It meant that simple and useful utility like calc became a visually bloated app with sluggish UX. That's an excellent example. A calculator does not need a loading screen, nor should it take over a second to start on any remotely modern machine. Fortunately MS have released the source, so you can see for yourself just how much bloat there is: https://github.com/Microsoft/calculator To compare, you can also see the source of the old "classic" calculator from Windows 2000 here: https://github.com/pustladi/Windows-2000/tree/661d000d50637e... That said, Windows CE was an attempt "to unify the UX", being basically a subset of Win32, and that didn't cause anywhere near the same level of disgust, so I'd attribute the bloat more to the cruft of "modern practices" than anything else.

Yes, the OSD tries to include legality in "seeing and modifying". If you regard Open Source as just "seeing and modifying" the source then anything that you can get the source code for is Open Source. This is most definitely not the case, as illustrated by my previous example of Windows 2000. Please see [0] and [1] for more info. Confusingly, there are still copies of the W2K source on github which have an MIT license in the root which is, I assume, false and unauthorized by MS [2].
