But the idea of storing any files in the cloud is very distasteful to me ever since the NSA Snowden story broke. Even something as innocent as a photographer taking pictures of a skyline or some beautiful architecture could land him in hot water if the government is looking at metadata and figuring out that he took lots of photos of a government building or a bridge or a power plant and randomly throwing him on some watch lists or no-fly lists. People have been hassled by the feds for a lot less.
My preference would be for all of these cloud storage providers like Google, Facebook, Apple, Dropbox, Amazon, etc to unambiguously and fiercely challenge the government on this and somehow unambiguously prove to people that they're respecting peoples' privacy and not complying with this stuff. Their denials so far have been obvious non-denials that are very carefully worded around "no direct access" when that's enough wiggle room to do just about anything.
Using some kind of cloud photo storage is a bad idea IMO until this gets sorted out.
