But that's what they are looking for.
If it didn't do what they searched for that would be spam, but it does do what they want. By being able to know a little bit in advance you can drastically improve the chance of success on finding what they want.
Also, sometimes there isn't an official app that does what the user wants.
Take Sky Q. The Sky Q app doesn't control the box. This app does. Nobody would find an app that didn't have "Sky Q remote" in the title searching for "Sky Q remote".
I think their policy is intended to stop someone renaming say a "calculator" app repeatedly as "Super top calculator app", "Best calculator app", "Cal-cul-ator" etc...
It's the same app, doing the same thing, with people searching for the same thing, therefore spam.
But that isn't the case with these apps
Regardless if you think it is, Google's reaction is over the top, unfair and harsh. It doesn't seem to matter how much they get investigated and fined, they carry on with what seems like absolute power.
