I get the intention behind the idea but the implementation seems strange. How are such developers going to find those testers? How will it improve anything regarding current state of apps in the store? What are criterias for those testers except for the fact that they exist?

Play Store needs better manual review from Google rather than such strange ideas. We’ve literally managed to push an app once which was broken after user authorization, and it passed the review process just fine. AppStore on the other hand kicked the build back at us the same day if not even faster than Google’s response which sometimes takes a week or two.

Additionally, Play Store is filled with apps that are an obvious scam, impersonation or outright ad-hell with semi-broken functionality.

My point is: we need proper moderation of existing stuff first, and this has to be Google’s job (wtf are we, as developers, pay revenue share to them?).
