This has been irritating me too...
For a while now, El Reg has been referring to Apple users as fanbois, regardless of context. Apple users complain about a bug and the headline reads "Fanbois howl" - how is that an accurate use of the term? Real fanbois deny all failings of their beloved whatever. Insult them when they have it coming, not all the bloody time!
Blanket attacking a usergroup actually seems a lot like fanboi behaviour to me (and don't start on me - I've never owned anything apple).
