Be careful what you wish for. I've covered the EU's legal action compelling Google offer "the right to be forgotten" before, but that right comes with a price.
After forcing Google to abide by the new laws, Spanish publishers' online traffic fell, but not for the reasons that you think. It seems that after the law went into effect in Spain yesterday, Google was forced to remove all Spanish publishers from the Google News index and closed the Google News site in Spain altogether.
This understandably made the Spanish publishers' online traffic fall, since their sites no longer showed up in a Google News display, but the drop in traffic isn't as bad as you think.
The site traffic across 50 online Spanish publications only fell about 10-15% overall, but that much of a drop in traffic is a big blow to the smaller news outlets. However, the Spanish publications weren't entirely removed from Google and you can still find them through a specific search.
But, the external traffic to these sites has fallen sharply, which could lead to a change or a full-scale reversion in the future. "[T]his suggests that readers are moving between different Spanish news sites more than they did previously, rather than coming to them from links at Google News and other sources."
