Isn't that how future is depicted in many instances? So going down that path is being "cool" and "futuristic" and "fashionable" and whatnot.I don't understand this stupid obsession app developers have with making their apps completely white (especially this ugly opaque glass style Apple seems so intent on pushing). All the apps end up looking the same boring colours. Facebook should just leave Instagram how it is and focus on cleaning up their disgusting main app which they just add more trash to every update then forget about it for another couple of months.
As for Facebook, it's hard to say that they are the ones really pushing for anything in particular (at least as far as design goes).
