So the current social expectation of most twitter users (app developers take note) is that an app should not post content without informing the user that they are going to do so; or without affirmative action from the user indicating that they want the app to take that action. I've seen people get outraged by apps that post without warning often enough to think that doing so breaks a fundamental bond of trust.

So the granting of permission is conditional on that permission being used responsibly, and if the app fails to work without that permission and then breaks trust with its users in that dramatic of a fashion...

I know that I won't purchase or use any Enfour inc. product in the future on the basis of this; there's plenty of easier dictionary apps that won't falsely accuse me of piracy.
