At first I too thought my drop in downloads was related to Kidoz, but it appears that it was just a coincidence that the algo change https://www.google.se/amp/s/www.xda-developers.com/developers-huge-drop-new-installs-play-store-algorithm-changes/amp/) occurred just after the Kidoz issues. Personally I don’t think Kidoz are any better or worse than other ad networks in terms of operational risk, they (and we) were just ‘unlucky’ that Googled reacted so strongly on the YouTube API issue.
