In law, you can only ever go after someone within your jurisdiction, and in this case either or both of the original source and a search engine that directs people to it would be required by law to comply if they are within that jurisdiction.
Ok, so your point is that as long as Google operates within a certain country, it should comply with all laws in that country? Take this one step further. Google operates in China, do you expect Google to comply with all Chinese laws, including censorship, as well? No of course you don't. Chinese law is applied on google.cn, not on google.com.
And this is exactly what's going on here, according to TFA, or even the summary:
Google currently de-lists results that appear in the European versions of its search engines, but not the international one.
This would imply that China (or the EU for that matter) is now forcing its own laws on the international version of Google. Which means that they would be grossly overstepping the bounds of their own jurisdiction.
And for what it's worth: there is no such thing as EU law. There are EU directives, which have to be implemented into local law by its member states. Which means that, assuming you agree with me on the China analogy, Google would only have to censor individual country-specific TLD search results such as google.nl, google.de, google.be etc. And what is happening now is that the EU tries to force Google to change the international version of Google, meaning it is attempting to shove EU directives through the rest of the world's throats.
