That picture is of "Max Schrems, the lawyer who successfully sued Facebook for privacy violations against European citizens" which is another article at that site. They probably just forgot to link it and give it an appropriate caption.
He did more than suing FB.
He helped to get rid of Safe Harbor and Privacy Shield because they didn't protect the data of EU users.
That seems to be Max Schrems, the guy who successfully sued Facebook in the past [1], but it's odd the image has no caption.
