I have apps that probably update everyday because I allow it to. And it does so in the background, at maybe 3am. Some updates I set that they need to be triggered before proceeding.
I think the worst part of all this is how intrusive the prompts are. It's not so much that there's always an update, but the fact that they're always in your face. And while you do have that option whether you want it or not, you are forced to make that option as soon as you run the app vs say having a notification in the toolbar.
