Facebook has access to the private messages that users send through the messaging platform, this being highlighted very clearly after the FBI obtained a court order to receive a user's private messages, and received them.
Facebook provided the FBI with information about one of those who entered the US Congress at the beginning of the month, and among the data it was able to provide were the private messages of that person, although theoretically that wasn't really possible.
Facebook boasted that Facebook Messenger has encrypted messages, and that no one can read them, but the reality is that everything is nothing more than a big lie, and the company can access our private messages whenever it wants.
Facebook sees everything we do within the social network, whether it's about private messages, from chat, or from other posts, so all the lies about encryption are exactly the same thing, and it's good to know this.
“In a criminal complaint filed Wednesday against New York resident Christopher M. Kelly, a search warrant was disclosed on his Facebook account. After being made aware of Facebook posts from an account of Kelly's containing images of him storming the US Capitol on January 6, the FBI searched his private messages as well as the linked IP address, phone number and address Gmail. Among the data provided by Facebook were private messages with other users."
