If you look in the settings of applications like Pages you'll see a section named Contributions, they list opensource projects they use even for those whose license does not require to be mentioned.
While I'm agree with you that credits must be given where it is due, stretching it to the fact that this behavior would be in their DNA seems not backed up by facts in my point of view.
Really? The same Jobs who asked Stallman personally about whether or not Next's modifications to Objective C would need to be contributed back, and who then made sure they were contributed?
If Steve Jobs were still alive, he'd probably be pledging to deplete every last dollar of Apple's billions to run this stolen product into the ground. Who does OpenStreetMap think they are, anyway?
After making this comment I've come back to my 'comments' page from time to time and watched its karma value gyrate between positive and negative.
Do the down-mods represent people operating in good faith thinking I'm being mean-spirited, rude, and damaging the conversation? Or are they Apple fanboys upset by a little uncomfortable teasing at their expense? I can only speculate. :P
Personally, I just don't know what to make of your original comment, serious, or sarcastic, the clarity of what you are trying to get across just seems quite low.
