Fresh thoughts

I just can not understand what is the point to publish the text of the article on Habré, which was written by another person, and make a link to it? Of course, I understand that if a person has found an interesting device or site, and wants to share it with others, this is certainly good, but when they simply take and copy the text of the article from another informational or news resource. I, for example, are not interested in reading a post in which the thought of the author who directly published it on Habré cannot be traced.
