Article 11 is about a new right for publishers. It could potentially make an infringement to post a link to a news article on Twitter, the paragraph you posted is a limitation to that right, because it says that authors can do that what everybody always could have done.

This new right was "tested" in Spain and Germany. In Spain news sites lost 15% of their traffic. Bigger site were hit less hard because people knew them and got to them directly. In Germany they gave Google essentially a license for free because Google didn't want to pay and because the publishers couldn't lose the traffic from Google. But smaller companies than Google and start-ups had to pay, putting them at clear disadvantage. Also the scheme costed around 10 million euros in legal fees had almost no income for the publishers. A Massive failure.

But they passed it anyway yesterday.
