Big companies are hardly ever coherent, let alone after a big pivot like Nadella’s.

The two things are also not exclusive: it might well be that MS “loves OSS” and that the ReactOS kernel was lifted wholesale from a Windows leak.

Besides, there are many who think projects like ReactOS or Mono are actually a net negative for the FOSS ecosystem, since they reduce the pressure on developers to switch away from Windows-based stacks.
