Because an MKL license is required to redistribute MKL. If someone wants to
include the binaries in their product they must acquire a license. An
MKL-based binary wheel would be for end-users that wants to install and use
NumPy. It would not be for those who redistribute NumPy as a component of a
larger application. ATLAS and OpenBLAS are free, and Accelerate Framework
is a part of Apple's operating systems. Those binaries can be redistributed
by third parties without Intel's licensisng restrictions. But if you are an
end-user installing NumPy for your own work you'd want the MKL binary wheel
instead.
