According to Google PlayStore, apps that contain or feature user-generated content (UGC), which include platforms like Twitter, Facebook, and Threads, must implement robust, effective, and ongoing UGC moderation. Google describes UGC as the content which is contributed to an app by users and which is accessible by “at least a subset of the app's users”.
So... All XMPP and email apps on Google play are in violation of this and Google just hasn't noticed yet?
