I know many people, a lot of doctors, who say that they would prefer to just be allowed to die when the time comes. Not everyone expects to have their lives extended by modern medicine and even if you do get longer to live, it usually isn't very pleasant anyways.
or even just taking cholesterol medicine, or having skin melanoma removed. I doubt many doctors are thinking "whelp, I have high cholesterol, guess it's my time to die"
That doesn't have much to do with him using non-free computer systems though.
As a side note: the pendulum is swinging the other way in regards to cholesterol - so in many cases doctors are not actually concerned about high cholesterol in the same way they used to be.
Oh yeah that is a little more complicated. I'd still imagine that he might choose death, I suppose that will be a real test to his ideology if it ever occurs.
