> I'm arguing that their handling of GCC and refusal to support it as a library directly motivated the creation of LLVM and led to a scenario that better supports the creation of proprietary software

I'm sure they are well aware of that. I don't see how they could have handled it differently without compromising their core values. Allowing GCC to be wrapped by proprietary bits would be unconscionable since it curtails user freedom (to modify & improve the software).

The differences in core-beliefs between Apple and FSF are irreconcilable: the former is pro-Tivoization and the latter is anti-Tivoization. Your stance on Tivoization ought to be a fair indicator on which side of the fence you stand, and no side will ever be able to convince the other side: at best you can agree to disagree.
