in 2018, Facebook told Vox that it doesn’t use private messages for ad targeting. But a few months later, The New York Times, citing “hundreds of pages of Facebook documents,” reported that Facebook “gave Netflix and Spotify the ability to read Facebook users’ private messages.”
Surprising? No. Appalling? Yes.
Let’s not forget how similar Facebook is to a CIA program that ended from public scrutiny only a few years prior, and how much involvement Facebook now has with US Government entities.
If the CIA wanted to kill
1.) Budding decentralization concepts and
2.) Cause overload to the system while Facebook retains ultimate control once everyone gives up or only a few small instances are left
This is how it would be done.
