Microsoft accidentially open-sourced their Augmented Reality app

The Microsoft employee who states:

> The third party notices file provides license information for third-party code that is in the Mixed Reality Viewer app, and the app itself is licensed under the Microsoft Software License Terms linked to in the “About” page.

is, of course, incorrect: if the GPLed third-party code is linked into the app, then the app itself must be GPLed.
