You are, as I read it, putting trust into the “independent“ third party that I do not. I understand the extortion these third put on people and businesses. Work says you cannot get promoted without a designation from third parties, don’t buy a lamp that is not UL certs, don't do business with a website that does not have certain add on’s or certs, the list is endless of these once valuable sources, like everything they too can become rotten and corrupt.If there's no independent 3rd party that tests products for quality and consistency then how do you really know what you've got. Unfortunately, I'd consider myself to be to skeptical of everything now and I didn't start with a big amount of trust in all human beings.
I do not trust them more or less than Berkey.
