How strict Microsoft is with enforcement of this license is another story.
> Previously, if the application you were developing was not OSS, installing VSBT was permitted only if you had a valid Visual Studio license (e.g., Visual Studio Community or higher).
From (https://devblogs.microsoft.com/cppblog/updates-to-visual-stu...). For OSS, you do not even need a Community License anymore.
You may not compile OSS software developed by your own organisation.
The OSS software must be unmodified, "except, and only to the extent, minor modifications are necessary so that the Open Source Dependencies can be compiled and built with the software."

> if you and your team need to compile and develop proprietary C++ code with Visual Studio, a Visual Studio license will still be required.
