iOS 7 update traffic

I don't see how operators could tolerate this, honestly. I can't think of a single provider who does not oversubscribe their access platform... Which leads me to this question :

Why does apple feel it is okay to send every mobile device an update on a single day?

Never mind the fact that we are we ones on the last mile responsible for getting it to their customers, 1gb per sub is pretty serious.. Why are they not caching at their head ends, dslams, etc?

The IOS7 upgrade is ~750 megabyte download for the phones/pods, and ~950
megabytes for ipad. There are quite a few devices out there times these
amounts to download...
