ProPublica’s new investigation calls into question Facebook's privacy practices and the encryption of its WhatsApp messaging platform. This article highlights several key findings that are not explicitly revealed to the $ 2 billion user base. Although WhatsApp has offered end-to-end encryption since 2016, there are certain circumstances in which 1,000 vendors using special Facebook software can read messages sent from one user to another.
For example, when someone reports a message, even in a private chat, the AI algorithm looks for suspicious activity related to terrorism, child abuse, etc. It then passes the reported message, along with four previous messages, to the real person for assessment. The user can then be either blocked, rejected or included in the watch list.
In a nutshell, WhatsApp’s end-to-end encryption may not be as waterproof as you can trust with constant on-screen pop-ups.
