What irritates me is that other companies get accused all the time of copying the smallest things from Apple, even microphone icons, gloss, or rounded corners.
However, Apple clearly was a late comer on many of these features, and they are inspired, and in some cases, downright cloned, and they're going to get a pass.
What if Google had a patent on Chrome's tab switcher and sued Apple? Or on a Power Controls setting pane? Or on cross-device open-tab sharing? There's be outrage among Apple users, because people just don't seem to see Apple building on other people's designs, because Apple presents all of them as major, radical innovations without acknowledgement of their prior existence.
I wish all of the claims of theft and copying would get dropped, I don't have a problem with Apple "stealing shamlessly" the ideas of others, I just wish they'd stop going nuclear when other people do it.
