I think the green party (Bündnis 90 / Die Grüne) will profit considerably more from this. They are know promoters of privacy and personal rights. "Die Linke" could also profit from this.
With Sabine Leutheusser-Schnarrenberger they also have the last privacy wall before the Constitutional Court.
They of course have absolutly no problems with corporate data mining...
If it weren't for their neo-liberal/laissez-faire approach to economics, I'd consider voting for them...
That would be a bit ironic, given that Die Linke includes former PDS.
(for those not following German politics: PDS was "Party for Democratic Socialism", formed from the remains of the old "SED" - Socialist Unity Party, better known as the ruling party of DDR and originators of Stasi)
I find it hard to believe them, though. They seem to be against anything as soon as it gets unpopular.
Also, if, during coalition negotiations, there is a choice between more privacy for everybody or Westerwelle retaining his post as Minister of Foreign Affairs, what will they chose? Bringing up that question is usually sufficient to get people to distance themselves from the thought of voting for the FDP.
