I think there are actually two interesting questions here since there are now many Pirate Parties in Europe. One about the general stance of pirate parties and one about the stance of the German PP specifically.

I would generally expect a pirate party to support free-of-charge publishing of snippets and linking to content on the internet as a basis for the open internet. On the other hand, I wonder whether the German Pirate Party is able to look beyond what may be construed as an interest of German publishing industry.
