Articles about this have been going around Spanish news aggregators for a while. Now that there's an official statement from Google, message will finally go around the world showing what kind of stupid laws the Spanish government is passing around with the influence of the powerful copyright lobbies.
Now, about the recent Spanish Intellectual Property reform. The particular reform affecting Google is actually called the AEDE tax. This reform will affect any news aggregator operating in Spain.
AEDE stands for Asociación de Editores de Diarios Españoles, as in Spanish Association of Newspaper Editors. This private association, together with another one called CEDRO, will take care of collecting this tax. Even if your publication is not associated with AEDE and because this reform is law, they will have the obligation to collect it.
This reform smells exactly the same as an old anti-piracy law. Just change AEDE for SGAE (another association, related to authors and editors). For a while, any kind of media support was subject to this tax. Any media support, including hard drives and even cameras, on the pretense that these might be used to store content subject to IP. This law was derogated on 2011, but not completely. Now it's the state the one who pays this tax to SGAE. I can see this AEDE tax having poor results, and either the public or the state ending up having to pay for it.
Funnily enough, this just shows how weird and different some people think. This tax is proposing that news aggregators cause loss damage to news producers just as torrent aggregators cause damages to Warner. Note that this IP reform also includes fines of around 150k to 600k euros for running a site that links to copyrighted material. Before, it was only an infraction if a site was causing "significant damages". This has been eliminated, as in, any damage is a significant damage.
Just as a remark, let's not confuse this with the so-called "Google Tax", which is related to stopping Google and other big co's from evading taxes in Europe and has nothing to do with intellectual property. To be fair, I do not even know by now, as they call "Google tax" anything that is going to affect Google, nevermind.
