I think that if the hurdle of using OSX to develop for Apple platforms is so high to one that they'd describe it as "fundamentally developer hostile", then yes.

It just doesn't make sense to me why anyone thinks they're entitled to have Apple build and support a complex developer toolchain on their platform of choice, and if Apple doesnt, it's a sign of "hostility".

I don't think Apple wants that person building for their platforms. As an apple user and developer, neither do I.
