I am still trying to imagine how google store would not check the authenticity f what they endorse to be published on their store.
It's their sole obligation before allowing apps being added to their store, they're should be strict reviews before letting anything.
before endorsing a thing like this, the source has to be confirmed and if it is not coming from the rightful owners of the branded name, it should not be accepted.
Precisely, it will assure the public that the application was safe since it was being provided by the real developers itself.
This is why I find it hard to accept what google store presents, except there is a directly link from the owners whom i trust.
I usually double check reviews and information regarding to the owner of the app that im going to download or install, better than being victimized.
