I think the problem isn’t that Apple gets credited directly from anyone in the know for things that they ‘borrow’ - it’s that the marketing machine that drives our consumerisms does such a great job touting the dumbest stuff and the users grab hold of it and believe it’s magic…kind of like the commercial where the guy is slowly swiping his thumb from right to left and from top to bottom of the iPhone 5 screen - we should have already known Apple would figure out the exact perfect screen size while everyone else blew it.
Samsung is starting to do a good job (via their latest ad agency) at breaking through the invented here perceptions and subtley mocking Apple for it’s claimed eccentricities.
