That answer is frankly a steaming pile of bullshit. Take this:

So this organization was built around the premise that the CIA could no longer operate and ‘promote democracy’ around the world the old fashioned way but now needed to use new methods and techniques which included the establishment of Non-Government Organizations to be able to continue to do without scrutiny by the public.

A plain reading of other quotes in the answer about the CIA is that the covert nature and problematic track record of the CIA is anathema to building open democratic institutions. The ideal of the NED is to be a more open and transparent organization. This pattern is repeated again and again: take a quote, then misread it to a level of incompetence that borders on malice.

They also equate the NED to the CIA multiple times without actually showing that is true. They show merely that the NED took over some functions that the CIA used to perform and do them in the clear. From what I understand, this happened in the 1970's and 1980's as the excesses of the CIA in the post-WW2 era were coming to light. Congress and the public demanded better behavior. The intelligence agencies have never gotten to be perfect angels, but on the plus side they stopped trying to mind control people with drugs (likely).

Then take this quote:

So here is an ‘NGO’ which is funded 99.4% by the US Government, doesn’t sound like much of a non-government organization.

This is a common structure in the US, notably with the RAND think tank. RAND is run separately from the US government but with a federal budget allocation. The advantage is having someone outside of government who can operate with some independence. RAND can produce ideas without being beholden to politicians or orthodoxy. China is looking into creating a similar think tank to generate ideas that would otherwise be shut down by the party. Given this person has no familiarity with this structure, my conclusion is they have no idea what they're talking about.

The sources are also sometimes extremely questionable. Take Paul Craig Roberts, who they cite for multiple claims of CIA involvement on behalf of establishing military bases, including Ukraine in NATO, and profiteering by taking over Ukraine's economy. Obviously the author's only criteria for inclusion was "agrees with me", because the guy is an absolute nutter. 9/11 truther, Kennedy assassination conspiracy theories, and has rather revisionist views of the Holocaust.

By relying on an article, you rely on their vetting of sources. They showed that they freely used at least one unreliable source.
