The main problem here is that companies have succeeded in their quest for changing who controls the computer, and, in other words, who really owns it. In the past, the computer was yours, and you decided what to do with it, and when/if to update (the Mac was one of the best examples of "my computer under my control").
Today, the World wants that the computer isn't yours anymore. Like if you must apply any patches even if you don't want to. Like if you are against the society, an offsider, a public enemy, if you don't obey.
Personally, I'm going to do my best so that my Macs are not patched (as I cannot sacrifice even a 1% of performance, and I don't have any security-risk from the data I have in my computers), but, of course, I take it for granted that it's not going to be easy to keep my Macs unpatched (except my Snow Leopard MacBook Air... the best Mac I have right now, as it's the one Apple controls less and I "own it more than Apple does").
