I often upvote articles I find interesting enough I want to see a discussion of them on HN. To me it doesn't mean every word of an article is perfect and above criticism, it just means it's IMO interesting and of substance enough to warrant discussion.

In this case I took my time fully reading it before posting it, but not being a biotech person I posted this here also because I was interested in criticism of flaws I would have no chance of not overlooking. But just flagging it isn't that. It doesn't tell me this article is bad, it tells me too many people aren't acting in good faith, so that raises the question why that is.

Trying to turn it around on others by speculating on what they might have done (i.e. why they upvoted it, if they read it), doesn't change what was definitely done (i.e. flagging it without any substantial criticism).
