At the heyday of the Snowden revelations there was a large outcry. When talking about opinions in Germany one always has to distinguish between the opinion of the citizens and the opinion of the government (these are often very different). Of course the German government has a very USA-bootlicking opinion about the Snowden question.
The fact that in Germany there (mostly) is free speech does not imply that the government is interested in your opinion. Take a nasty English joke about lawyers and replace "lawyer" by "politician" and you get the whole mentality quite well.
