This is troubling because there's nothing preventing a Chinese court from claiming jurisdiction over the page on 1989 Tiananmen Square protests. Of course that request will be thrown out because, well... it's China, but with the direction EU's taking, it's only a matter of time before western European countries start sending more of these takedown requests.
It's interesting because they would only appear that way to the EU itself. For ordinary people, especially in the United States (though I suspect elsewhere), Wikipedia is far more of a respected organization than the European Union.
(To be clear, I mean that if Wikipedia says "what we're doing is okay" and the EU says "what you're doing is illegal", I think more people are going to believe Wikipedia. That's an interesting position to be in, whether it's ultimately useful to you or not.)
