The argument against multiplayer is more complicated than that. By adding my multiplayer there is a chance Bioware short-changed some things in the single-player. Even using a separate development studio is no guarantee that they didn't forgo something good in single-player just to make something more workable in multiplayer. This might not have happened at all but it is a possibility, and since multiplayer was not needed or desired by the playerbase, the option seems wasteful. My own attitudes toward multiplayer have been adjusted somewhat, but that is the main argument in as few words as I can manage.
