Except it is not.
Look how adamant you have been about this "exposing the truth" and your blind support. Unless you've seen it, you really can't comment on the content.
Now, if you think that after PBS making the decision (without the Koch's involvement except for them being donors according to the kickstarter page) won't have any effect on an unfinished documentary, you're very naive.
Yes, it is - you have nothing relevant to say about that.
So let's take what you do say about the documentary.
Of course, none of us have seen the finished product that doesn't exist. So what information do we have to base any opinion on?
These are academy award winning documentarians, and PBS approved their documentary until the Koch brothers pressured them to reverse that decision.
That means this had passed the PBS process for being a fair project.
Now, let's note that no matter how fair the documentary is, if it has any criticism of the Kochs, some here will call those truths 'bias' and a 'hit piece'. So we won't agree.
But the logic you are advocating is that every unfinished documentary should be assumed to be a 'hit piece' and unworthy of funding.
You have no more reason to say this is a 'hit piece' that you would for any other film at this stage in the process.
There are remedies if it is. If the finished product comes out a 'hit piece', then PBS can say that and decline to air it. If it is and they air it, you can criticize PBS for that.
But what you're supporting here is simply assuming it's a 'hit piece' and supporting it not being funded as it otherwise would be based on nothing but the Kochs' interests.
And a critical documentary is not a 'hit piece' when criticism is warranted. If a film is done on Wall Street practices that led up to the 2008 crash, having some criticism is not a 'hit piece' necessarily. If a documentary is made about Jack Abramoff's activites that landed him in jail and is critical, that's not a 'hit piece' necessarily. Some things deserve to be critizied by a 'fair' documentary.
Often, the phrase 'hit piece' means 'you're telling the unplesant truth about my friend'. It's a false attack on the documentary.
There are no guarantees how this documentary will come out - but zero evidence of a 'hit piece'. It's attacked at this early stage for nothig but wanting to hide the truth.
The unlikely possibility it will be unfair is being argued as if it's a confirmed fact it will be to justify killing it before it's made.
The fact is, the Kochs have a significant political role in our society. A documentary about their activities is exactly what political documentaries are for.
The only basis for opposition to the documentary at this time is a purely partisan one defending censorship to hide the truth that might be bad for 'your side'.
