The extent of company representatives complying is debatable.  YET no doubt, for sake of argument, there's some sizeable groups within those companies who willingly wanted to censor, and/or went along.  

Yet, in no way does that remove or resolve the dirty FBI tactics.  The FBI were the ones performing those constitutional violations.  Hatch act violations.  Violating the purpose of the FBI, which is to Investigate.  etc.  

Just because the Dems were OK with the crimes of summer mobs, doesn't mean those were not crimes.  Arson. Assaults.  Beating up dissenters.  Even some murders.

In a similar way, those FBI censorship activities are still crimes & violations, regardless whether some companies went along, or helped.  And should not stand unchallenged.  Shameful to stain the FBI's long standing reputation for justice.  Some bad apples need to go.
