Too Long; Didn't Read
WhatsApp is an instant messaging application that Facebook owns. It is the third most used messaging application, according to Messenger People. The company tweaked its terms of service and privacy policy which notified users once they entered the application. It received a lot of backlash regarding the update which caused many users to move to other secure messaging applications, including Signal and Telegram which will be discussed later. WhatsApp issued a clarification stating that the new WhatsApp privacy policy would only affect users' communication with businesses and emphasized that personal chats and calls would still be end-to-end encrypted.
