Imagine a person who you know to have a large bias against something. Now imagine they tell you a narrative about that thing. You, being a reasonable person, would use greater scrutiny about that narrative than someone who you know to be uninterested or even marginally interested in the subject.
I agree that the public has an interest in finding out about issues in the rockets its government purchases. The above commenter isn't saying "disregard, it's the anti-SpaceX guy!" It's just more information. Gathering information has a cost; and we can't all fully research every opinion.
I didn't downvote you; it's a reasonable argument to make, and I don't mind giving the counter-opinion in the least.
