Not even close - look up COINTELPRO and how many of the letters that were sent by the discoverers of that information ACTUALLY made it, let alone how few that did make it actually got published. Hint : very few.

The media has always had to kowtow to some degree to local authority, and there is always the element of ‘the truth we choose to believe’ (or are being told to believe) being published over harder reality. The west tends to be more transparent than most, and more honest than most, but everyone is very far from, and has always been very far from, any sort of unbiased view.
