I am obviously a very small player doing things as a hobby, I don't matter to Google. But what I am pointing out is that they already take a cut of whatever few dollars I earn (beyond the initial $25 I paid years ago just to get on the play store). If you see the thread, the OP asked their customer support and they said: "Especially, since the response from customer service seems to suggest that the best way to get it removed is to run Google AdWords (which I am already running, btw)"

If the angle here is running ads and if they are already taking a cut, why are they doing this? If the angle is security, why not test the apps and have them removed! And in either case, why keep the developer in the dark? And why is there no way for small time insignificant devs like me to know how to get rid of the banner!

I think "Bank of 4merica" shouldn't have been there in the first place. Especially for a store that is running billions of $$ worth of transactions. This is Google, again, pushing a cost that it has to pay to external actors.

Why would they allow this hypothetical app in the first place?
