I've responded elsewhere in the comments about my positive experiences (just ⌘+F) but I think the main reason people aren't typically in "public" about their role at Apple is because Apple has a secretive culture. You're just expected to not talk Apple's business, including what you work on, to anyone outside of Apple (or even people inside Apple if they're not disclosed on your project.)
Trust me, complaints about this come up a lot inside Apple. I'd love to go to conferences and talk about the tech we're working on. (Even if just to get more hires!) I'd love to blog about it. I'd love to contribute to open source projects. But it's just not what we do here, in general. (Hell, I had to make a throwaway just to post this on HN.) It's definitely my biggest complaint about my job, and it's definitely kept us from being able to hire good talent.
