The worst cases seem to be when there's an article (seems like it's always on Medium) about some complicated multi-part technical thing going wrong, a top level comment slings blame around as if they know exactly where to sling it and uses a PopSci understanding of the subject matter to justify it. Then someone who actually knows the relevant industry says "well actually it's a little more nuanced", proceeds to explain and then gets down-voted and flagged for it. Seems like a great way to send the message that technical knowledge and experience is not welcome here if it's going to go against whatever the convenient narrative is. What it definitely doesn't do is instill trust in comments about things I am less familiar in.
