The commentator comes here with some assumptions, perhaps some hearsay, and an emotional attachment to their position and make the statement as though it's fact.
In this comment, you know what's missing? Actual knowledge, actual reasoning, and actual facts to back up the his/her claims. Perhaps worse, there are some facts (Ibuprofen suppresses some immune system responses to infection) which are used to draw unsubstantiated conclusions about the commentator's opinions (Ibuprofen can cause severe forms of Covid-19 in young people).
From where did this "related news" come from? On what rational basis do you draw the conclusion that an across-the-board recommendation not to take Ibuprofen is warranted? How does that trump other factors that may be at play?
What I really worry about though is how many people will read the comment I'm responding to and go on to post elsewhere, "in related news...", with a similar air of self-certainly and casting of opinions as facts. In other contexts of high emotion, people get lynched because of this sort of social media posting, people may cause themselves harm because of this kind of posting.
By the way, the commentator may actually be right... but there is nothing in the comment to make me believe that his/her being right would be anything more than coincidence.
I'll leave with the personal observation that this community is suppose to be made up of "the smart ones"; which we ourselves so often confidently believe to be true that we all too frequently think we should be able to engineer society and solve all its ills. If there is any one ponder-able to take away from reading Hacker News on regular basis, it's how decidedly average even "the smart ones" can be on any given topic.
