Anyone have any info on Amazon's security practices for their cloud/photo storage? I'm slightly more tempted to go with them to store my photos than Google, if only for the implicit contract that I'm paying them to be a Prime Member and hence paying in some way for the storage, so they should in theory be less likely to try to profit off of my photos...but I'm also still paranoid.
