Could be, but still it reeks of overreaction. Without the need of seeing anything else, it’s almost impossible that Germany’s law is that strict that “linking to (discussion of) pirated material” would be off, since if that was the case Google would be making Germany rich with their fines, which doesn’t seem to be the case. It’s even worse when it comes down to saying “discussing or mentioning” internet piracy would be illegal - under the way copyright holders themselves understand it, this would mean mentioning the market of secondhand sales would be illegal in such jurisdictions.
