Apple has also offered their last two versions of OS X for free (I'm counting Mavericks that is now on public beta) and has never charged Aperture/iPhoto users for Camera RAW updates.
This is partially true. With OS X, the raw updates do come with the OS. However is is also true that at some point, Apple puts a base version of Aperture you must have to use this raw support. If you are still using Aperture 2.x, even though OS X has support for the latest cameras (or close to it), you can't use them in Aperture 2.x though you can in Aperture 3.5.1.
But in general Apple gives raw updates for Aperture for 1-2 years back, while Adobe stops adding new cameras the day a new major version comes out. You can use DNG but that has the drawbacks as I mentioned above (it strips some OEM metadata that I personally use, and have noticed). I tend to be an early adopter and thus wouldn't stay on an old software version when a new one came out, modulo huge work-stopping bugs, so I may be less angry about this than some
