They need to be called out on this. "Everything is a remix" was brilliant in exposing Apple hypocrisy in this regard.
The thing is, Apple fan(atic)s (the pundits and those who echo them, really) love the "Apple innovates, never copies, only bad companies without any talent copy" routine, and here we have an example where Apple has pretty blatantly ripped design elements from their competitors. For the people riding the "everything Apple produces is unique and amazing" train, iOS7 is a deep betrayal specifically because it is so familiar to things that others did first.
That is the primary reason I think Apple is getting so much crap. Apple claims to be the industry leading innovators; Tim Cook even said during the D11 conference "I don't like copying. It's a values thing." in reference to Samsung patent litigation. Apple partly built it's reputation on bashing the Microsoft (Switch campaign) and Android (WWDC's and MacWorlds). Now that Apple is playing catch-up in the mobile space that they essentially pioneered, they are getting the same snide back-handed remaks that they were dishing out.
Following current design trends and adding a splash of your own flavor to them... that's status quo, isn't it?
"Some of their own medicine" as it were.
While iOS 7 may look more like WP and Android, anyone who uses it can tell it still feels and works like iOS. Apple harp on about how design is more than how it looks, and it especially applies in this case as it doesn't work anything like Android or WP. But use a Samsung Galaxy S, and you can immediately tell that their apps menu is a wholesale ripoff of the iPhone's Springboard with next to no effort put into differentiating or improving the original design.
I agree, but the similarities are being pointed out precisely because Apple (and their major pundits like Marco and Gruber) makes a big deal about how others have borrowed ideas from them.
For example, the infamous "Redmond/Mountain View, start your photocopiers" lines, and Marco/Gruber's frequent quips like "Hmm, I've seen something like this before..." in regards to something Google or Samsung has done.
Apple's smugness is what's getting them, not their borrowing of ideas, itself.
