I don't think that's true (at least not in practice), because if it were, then problems like https://news.ycombinator.com/item?id=37267940 and https://news.ycombinator.com/item?id=37394919 wouldn't happen.
The two examples you provided are a problem, but so is the current CNA system that is an inherent conflict of interest.
If I was affiliated, I'd want to see a POC for whatever someone was claiming.
