Er - so there is a fair use defence for using short quotations from articles, but linking to the source so that the reader can see the whole context of the quote may be a copyright infringement? Sounds really sensible to me.
"Fair use" is a USA copyright idea. In Ireland (& UK) there is a weaker "fair dealing".
Annoying the US constitution is nicer about copyright, since it says that copyright is explicitly for limited time, and that it's to benefit the arts & sciences. Whereas the European Charter of Fundamental Freedoms (which was only enacted recently), just states that "Intellectual property shall be respected". No limits, no purposes. ☹
Fair use doesn't exist in EU. There are certain provisions of copying allowed for research and a few select reasons but its much more restrictive than the US.
So if they had used quotes from the article they could genuinely be in trouble.
