It sounds like Apple Photos "phones home" by fetching some indices? It doesn't sound like photo data leave the device, but I think Apple's issue is they should have been more clear about how this feature worked and what data is and isn't transmitted.

If it works how I think it works, I actually don't see an issue here. I don't think anyone here expects there phone to not "phone home" to check for OS updates by default?
