Well windows does not come with every PC either, it is perfectly
possible to buy a PC with no OS installed, or with some other
OS installed. Sure, most people do buy with NT or Win98
installed, but I don't see the fundamental difference
issue here at all.

When we talk about the only free solution being GNU/Linux + GNAT
we are not talking about price (gratuit), we are talking about
free software (libre). It is an important distinction.

In terms of price paid for proprietary software, it makes little
difference whether the cost is included in the hardware you buy,
or you have to buy it separately as far as I am concerned. You
are still using proprietary software that costs you $$ and does
not give you a free software solution with either definition of
free :-)
