It wasn't really a conscious choice on my part, I had to get the subscription since I needed to collaborate on some files with people who were using it, and it forces you to add shared folders to your own Dropbox if you want to use them for collaboration, causing them to count towards your quota which is very annoying. So I thought I might as well use it as a backup location if I have to get this subscription. I don't really expect privacy from these services, I guess it's a tradeoff.
