The article is hilarious on this point. "This just in! OS update kills phones, curdles milk, terrifies children! Also, users might be angry that they're not getting it right away!"
By the way, I shouldn't need to say this, but the plural of a terrifying anecdote is not data. Every upgrade ever pushed breaks something for someone, and the noise from one failure sounds louder than ten thousand successes. We'll see if this dire emergency still looks as bad three days from now when more reports are in.
