I've read the responses from Google that the developer copied and none of them clarifies exactly what's wrong. If this is really the issue then they should have explained it clearly instead of saying that the app is a spyware.
This seems to be the root problem with Google Play's developer experience - no matter how much you ask them what is wrong, they will not tell you (despite this being straight-up illegal in Europe).
You get a copy-paste of the same non-explanation as a non-answer, which is presumably either automated or being sent by a human with no understanding of anything, and therefore might as well be automated.
