I completely disagree. The developer offers the same version of their game for free to everyone. Donations are solicited, but people who donate don't receive anything in return. In-app purchases have value to developers to verify payment validity and function as DRM to prove the user did purchase a thing, and they have value to the user to provide legitimacy to the transaction and assure that if they don't get what they paid for, there's reliable customer service to help them. None of these things are relevant when users donate. So what's Google's role in this? If they're OK not getting a cut of subscription services paid for outside the app, what's the problem with not getting a cut of transactions users get nothing out of?
