It won't been obscene amounts, the free tier's quota is only 10GB. the
music which is probably the thing that moves into the the cloud the
fashion you described isn't moved into the cloud by uploading.
I'd expect the reads to dominate over writes so your traffic pattern
asymmetry is preserved.

having customers that want to use your service is rarely a bad thing.
One of the things that this discussion point misses is that when you
operate at a distance from your data, you become rather sensitive to
latency. while apple is rather good about caching data locally, that
doesn't eliminate it from consideration.
