In so far as this is true -- that Android devices' pinch-and-zoom doesn't behave at all the same as iPads', and that this makes them much worse to use -- those Android devices have not copied what Apple did.

(I have no opinion about how much Samsung actually copied from Apple or whether what they did was legal; I haven't looked carefully enough at the case. I'm not passing comment on that. Just saying that you can't reasonably say both (1) that what Apple have rights over is a very refined implementation of pinch-and-zoom that differs from anything you'll see on an Android device, and (2) that a maker of Android devices copied it. At least, not without a further explanation of how they screwed it up so badly.)
