In fact, I prefer Dropbox's Camera Upload. With Dropbox, when I go home and sit in front of my computer, I find my photos as actual files existing on my computer. Google, on the other hand, is trying to make it very convenient to share them on Google+ and very inconvenient to download and store them locally. They don't even sync it to Google Drive as files. They are trying to eliminate the concept of "file" from the users' mind, just like Apple.
