Google permeates all of digital life and has been in our pockets every day since the extreme popularity of Android smartphones. Thus, the search engine giant has a lot of control over which apps get onto your phone via Google Play and which don't - in most cases, of course, this is about user safety, so that no malicious applications are distributed. But there are also apps that Google just doesn't seem to like.
This includes the alternative app store called F-Droid, which is not available for download from Google Play. The app is a kind of alternative shop where all the Android applications offered are completely free.
