You are drawing the wrong conclusion here. CPython has been using MSVC many years before Microsoft even started to sponsor MSDN subscriptions for core developers. MSVC is the default Windows compiler for over 20 years now. IIRC Microsoft started to donate MSDN subscription for about 5 years and Steve has been helping out with Windows improvement for about 5 years.
