This has nothing to do with the article. This has to do with sources the poster chose as evidence to support a position. It is definitely relevant to question whether a poster has read and understood their own citations, particularly when those citations are not very good or contradict the poster.
It's very relevant if the OP read the article or not. Makes his/her argument stronger/weaker because the articles are used as basis for the argument. So 'Did you even read the article?' is a valid question.
