IF that is the case, I'm actually willing to be slightly inclined to see this as a positive? We should normalize installing apps outside of Google Play, but that means malware becomes a serious issue with people downloading and installing random APKs.
e.g., this may normalize people hosting downloadable APKs whilst also reducing malware risk for "normies", which idealistically could weaken the "monopoly" of Google Play on android.
The problem is that Google is the gatekeeper.
In fact, you may not even be able to use any apps that interact with Google Play Services, which includes almost every app on the market.
