Like all social media type companies, Google operates as a Ministry of Truth:

Google removed at least 100,000 negative reviews of the stock trading app Robinhood from the Google Play app store after angry users sent a flood of critical reviews that caused the app’s rating to plummet on Thursday. The app’s rating went from roughly four stars out of five on Wednesday to just one star on Thursday. Robinhood users were understandably upset after the company halted purchases of GameStop’s stock and other stocks promoted by Reddit’s WallStreetBets community.
