It’s the Intel MKL, I don’t think Intel has ever even endorsed using it on other vendors CPUs, much less claimed that it is “fair” or “neutral”.

Well:

    On November 12, 2009 AMD and Intel Corporation announced a comprehensive settlement agreement to end all outstanding legal disputes between the companies, including antitrust and patent cross license disputes. In addition to a payment of $1.25B that Intel made to AMD, Intel agreed to abide by an important set of ground rules that continue in effect until November 11, 2019. 

    Customers and Partners

    With respect to customers and partners, Intel must not:*
    [...]
    Intentionally include design/engineering elements in its products that artificially impair the performance of any AMD microprocessor.

I like that 'in effect until November 11, 2019.' part :D
