A lot of what you said in the second portion isn't at all true (for instance, Google definitely doesn't just ask the author if what they are uploading is malware as a sole check if an app is malware). But I don't think we can even continue the discussion until you prove the "obvious" assertion that there are apps in the Play Store that are malware. So I am going to ask again: give a single name of an app currently in the Play Store that is malware. We are not talking about Apple, but I will extend it so that you can give an app in the Apple App Store that is malware as well.

Let me know when you can provide a single specific name.
