The decision said that a link to illegal content can be illegal in itself when 1. it's done for monetary purposes, and 2. when the person creating the link was aware of the illegal nature of the content being linked.
But who would have doubted about that? Did you really think you could create links to illegal content for money and get away with it?
On the other side, it clarifies the fact that a link to illegal content will not be illegal if it's done for free, or if it's done without knowing the illegal nature of the content being linked.
To quote the decision : "it is to be determined whether those links are provided without the pursuit of financial gain by a person who did not know or could not reasonably have known the illegal nature of the publication of those works on that other website or whether, on the contrary, those links are provided for such a purpose, a situation in which that knowledge must be presumed."
From my perspective, it's a good decision.
