It's because the last few versions of OS X and Apple's applications have seen bigger changes than previous versions. And a lot of the more hardcore Apple fans tend to dislike change. A lot of Apple's more long-term fans hated OS X when it first came out, too. I'm not trying to bash Apple fans when I say this - I'm an OS X user too, and admittedly I only finally moved on from Snow Leopard last year (I actually like a lot of the changes, and most of the ones I don't like are ones that are easy to ignore). This phenomenon is certainly not exclusive to Apple fans either - just look at how many people still refuse to upgrade to Windows 8.
