These people were true fans. SOS were like the starmen.net
of the anime community. Letter writing campaigns, contacting people in the biz, and generally just doing what needed to be done. All they wanted was Sailor Moon in america.
Meanwhile sub groups are all about speed and getting their asses kissed and standing up to "the man". What good have they done for any anime? None. Nothing but leeches. Do they even care about the series they sub? Do they push for said series to be fully released in other countries? Of course not.
