Another one who cares only about himself and developers, not users.

As a developer, I can understand he wants as many users as possible, so creating an addiction-like shitload of motivation and triggers seems reasonable.

As a user, I'm perfectly happy with apps like Dropbox, which do their job when I need them, but don't bug me when I'm not. I'd rather have an app I rarely use over an app which bugs me all the time or tries to steal my leisure..
