We're talking about mass censorship of artistic output for which there is widespread international consensus (basically all of the global west) around being both harmless and protected. The app in question very clearly does not allow gambling! The fact that the app depicts a slot machine is a red herring.
Such censorship is being carried out against millions of humans, by one of the few organizations on the planet large enough and resourced enough to take principled stands against same.
Google actually left China for this reason specifically. The correct answer by the same organization in question is not without precedent.
This is not a small transgression on Google's part.
