That’s great but this is Android. I don’t want to install random apks from Github. Google, Fdroid and Izzy are trusted stores that people have been using for decades. Sure, there are better stores and newer technologies. It’s great when apps distribute over these stores to. But why artificially remove options? Shouldn’t it be up to the customer (and their threat model)? Afterall, I’m getting the app from the store and not the store for the app.
