I am mostly pro-Google and against many weirdnesses we have here against companies with our laws. I try to explain what is going on here.
In Germany a company which has a web presence needs to have a so-called "Impressum" with essential business data and a way to contact them in a reasonable time. When there is a phone number, it needs to be answered. Emails need to be answered soon, too, when there is only email address as contact possibility. The impressum is regulated very stricty to prevent fraud and anti-competetive practices. So it is generally not that bad, except that it abolishes anonymity.
My opinion here: In fact, Google is avoiding its users. Have you ever tried to contact them? In this case it might be a good idea to give people the possibility to contact Google somehow.
And to the people joking about Slashdot. Yes, also Slashdot would need to have an Impressum page when it had a subsidiary in Germany.
