Exactly! People install software onto other systems every single day onto systems that do not have capability-based security (including iOS, for the record, which gives application a lot of implicit access to data like your address book), and they never think twice about trusting it, but as soon as you mention what is available to the app, even with an explicit and well reasoned statement about why you are getting access to something you aren't using, people (like this poster) get /angry/, not just confused but /angry/, and start taking positions like "I will not install your software at all"... it's pure madness.
