For example, I never asked for Google Streetview to photograph my property, so in that sense they might have violated my privacy.
But clicking a Like! button is like giving implicit approval to send some relevant data to Facebook.
If you were a German Facebook fan, would this law make it impossible to place a Like! button on your own site, when you and your visitors clearly want it?
Is it possible to voluntarily wave away the right to privacy or is it really an all-or-nothing deal?
Edit: It seems that you get logged without ever clicking the button, or lack a Facebook account...
The paper "Facebook Tracks and Traces Everyone: Like This!" mentions 3 valid privacy violations by Facebook.
informational self-determination: the individual should
be able to decide which data are disclosed to whom and
for what purpose.
contextual integrity: data has to be treated according to
the norms applicable to the context in which
the data was disclosed.
data transfer without consent: data should not be
transferred to another context without the individual's
consent
Abstract: [the Like button] is also used to place cookies on the
user’s computer, regardless whether a user actually uses
the button when visiting a website. As an alternative
business model this allows Facebook to track and trace
users and to process their data. It appears that
non-Facebook members can also be traced via the Like
button.
