I understand what you're saying, but these things are news. I could post my version of the news, as others on this board do, or I can expose people to what is actually being reported. I think providing a link to the source material is actually more useful. Any time someone makes a fact-based post that the reader doesn't like, they respond "Link?" This happens both directions. Why not skip a step?
I could provide a link to the article to which the link refers, but I think the tweets provide a clean, visually-appealing summary of all of that.
