I would like to point out how the PPSSPP project circumvents this problem. It's an open-source PSP emulator. They have the a free version available on the Play Store here: https://play.google.com/store/apps/details?id=org.ppsspp.ppsspp https://play.google.com/store/apps/details?id=org.ppsspp.pps... They also have a "Gold" version available: https://play.google.com/store/apps/details?id=org.ppsspp.ppssppgold https://play.google.com/store/apps/details?id=org.ppsspp.pps... These two apps are functionally identical, only difference is the logo and that the "Gold" version costs money. So if you want to contribute some cash to this project, you just buy the "Gold" version. Other open-source projects could adopt this model too to evade this policy. The price you pay however, is that a part of the money goes to Google. Which is obviously the reason why donation links are not allowed in the first place.
