I disagree Ronny. I have been using the All in One Adsense and YPN plugin for sometime now and even though I was a newbie to WordPress at the time, his donation method was very clear and up front IMO. When you install the plugin and go to the settings screen, the option to share your ad revenue with the author is plainly shown and he explains how it works and lets you opt out if you don’t want to share. Yes, the setting is defaulted to share the revenue, but why would you activate a plugin and then not go to the settings page, where you would easily see this? Nothing hidden, nothing sneaking going on here as far as I’m concerned.
