Bravo for your transparent and open approach to user feedback. The standard these days seems to have fallen low, with countless companies implementing sneaky ways to exploit users however they can, with sugar-coated, obfuscated language. It's refreshing to see such honest replies from this project, especially considering the question is about how to avoid participating unwittingly. I also would prefer not to share bandwidth in this way without knowing, but as you described in another comment, I see there are real positive benefits when used ethically.
