So even reproducing the full title of a news article would likely be an infringement, and then that becomes another thing platforms take liability for/need to filter under Article 13. Whether there's a link or not would be irrelevant.

The behavior of publishers in countries where they won this battle is telling: a when laws were passed in Belgium and Spain requiring aggregators to license even small excerpts, Google stopped, and the publishers didn't take very long to offer free licenses.
