Does it really matter with whom they colluded? Why is the FBI doing censorship at all? I guess collusion with foreign actors might make it worse, but they are already way out of bounds to begin with.
The FBI is America’s KGB. They are our state security agency.
We have a huge, ideological, activist Fed.gov - what did we expect?
Every massive government, since the beginning of time, has an internal intelligence/security service which protects “the realm.” Its job is to know everything, estimate all threats, and protect the power of the Party and government - sometimes from peasants, sometimes from foreigners, and always from high-level players inside the government itself.
While of course not completely the same, the KGB is an apt comparison for what DHS and the FBI have (and will) become.
