A "faux pas" (n.b. no dash) is a mistake made in a social situation. it is not simply a fancy way to say, "thing I don't like", which appears to be the way you're using it. Nobody outside of Apple has spent a week living with iOS 10, and even then, it's still a beta. You're working from a few tens of minutes of video footage. I liked a lot of what I saw in the keynote (even more so things in the "Platforms State of the Union" and numerous sessions throughout the week). Out of all the recent iOS releases, iOS 10 could be characterized as the "Christmas Morning" release, with tons of small changes that users (and especially developers - it is, after all, a conference for developers) have wanted for a long time. Outside of this thread, I have seen a lot of positive reaction to everything shown at this year's WWDC. But we get it, given a few minutes of preview video, you hate iOS 10 because it doesn't appear to be exactly like iOS 9 (actually, you're making a good argument for going back to an entirely closed/NDA'ed developers conference, to avoid months of semi-informed complaining about beta software). But please don't try to make it sound like you know what's best for everyone or that you can speak for what everyone wants.
You, and some others here, keep trying to make it sound like "tweeners" and inhabitants of Asia aren't real actual people and anything that might appeal to them is bad and should be avoided, or, at minimum, ought to count less than things that appeal to us "real actual people". How condescending. I am not a "tweener". I have never even been to the Far East. And I like much of what I've seen of iOS 10. How about you stop trying to condemn it with an air of authority and start saying, "I don't like it" - that is an accurate and undebatable statement (and if you can do it in a Dana Carvey-style crotchety old man voice, so much the better).
