That's like saying that Android preaches the nix way because it runs a Linux kernel. This is obviously false since the interface presented to the user pushes a completely different way of working and thinking. Using any of the listed software requires knowing what you're doing. It's the same situation on Linux and Windows, you can install PHP or Python all the same and need the equivalent amount of knowledge to do so. If you seriously can't see the 'Apple way' then take another look at their whole business model, which is making things simple enough for people with little training to use. The nix way consists of understanding how the system works, which is in direct opposition to the Apple way.
