Losing a civil case is not proof beyond reasonable doubt, but a 51% preponderance of evidence. A company can lose a case, and still not be guilty - why apologize for something you're not guilty of?
At least in German the word "to apologize" ("sich entschuldigen"; although this translation, though often used, is considered to be impolite; if you are interested in the details read http://www.spiegel.de/kultur/zwiebelfisch/zwiebelfisch-entsc...) has "Schuld" ("guilt") in it. This implicitely states the belief that there exists a concept as guilt, which I don't, since I don't believe in free will.
