Article 11 targets news aggregators and search engines. Unlike blog posts or newspaper articles, they generally cannot benefit from the right to quote [3]. Article 11 has two goals. One, it aims at protecting pieces of a work that are generally too short to enjoy regular copyright protection; second, unlike the usual practice in continental European copyright law, it grants ancillary copyright to publishers, not authors, for easier enforcement of these rights.
Note that this does not mean that I endorse Article 11 (I do not and actually consider it harmful and the result of misguided lobbying), but we should be clear what we are actually talking about.

[3] As the Wikipedia article above summarizes it, "the resulting new work is not just a collection of quotations, but constitutes a fully original work in itself".
