Sure, but why? If the rules clearly said "no chess games", one could say "that ends the discussion of why chess games are denied", or you could further ask "but why are no chess games allowed?". Is it because Google plans on having their own Google-Chess someday and thus is preemptively preventing competition? Is there a technical or regulatory reason chess games aren't allowed?
That's the question (at least for me) here: why are (non-tax-exempt) donations not allowed, beyond the tautological response of "because the rules say so"? I'm not familiar with the regulations around this area, so for all I know there's a great non-Google reason for this and Google just wants to avoid the hassle of conforming to some law. Or maybe donations is a feature they want to eventually support in Google Play and they don't want to have to force a bunch of apps in the future to switch once they add it (which would be a more disappointing reason). Perhaps they're afraid that it would create a loophole where people could get around the 30% cut since psychologically it feels shitty for someone to middle-man a donation, but then if they made donations Google-tax free, everyone would just choose "donation" and they'd have to police this.
