Duopolies offer you a whitelist
I wouldn't trust a whitelist from Google because their interest is purely profits. If the Play Store is Google's idea of a whitelist, it's already an epic failure. Most apps contain malware imported from 3rd party ad managers and cloud tools. Flagging an app as abusive doesn't seem to do anything. Apple's store is cleaner but any device locked into it is crippled by Apple blocking anything that competes with inferior Apple offerings.
This will probably have to work like network blacklists. You subscribe to the ones you like and it's purely voluntary.
