many people here don't read the articles, and that's not going to change. (on today's internet, jumping from the site you want to be on to a site with unknown UX patterns is fraught)
but people here do read the comments, so having important details from the articles in comments here improves the quality of comments here, at least if you value staying on topic.
I think mostly the point is that it inadvertently implies that the message adds something new. A note that the same thing was posted on LinkedIn would help the ones tho did read the linked content know right away it's the same. I managed to just move on, but I did had a knee-jerk moment of "what if I'm missing something?" - I suppose for some people it's more difficult.
