Where's Marvel?

I was reading this year's Liberty Annual by the Comic Book Legal Defense Fund, when I noticed the list of corporate members.  It has most of the large comic book companies such as DC and Image listed, but one stood out by its absence:  Marvel.  I'm not quite sure why that is.  Presumably Marvel's against censorship as well, but maybe their Disney ownership is squeamish about supporting an organization which defends freedom of expression right up to its extremes, which is, of course, where it always has to be defended as nonextreme expression seldom is censored.  In any case, the comic is a good read.  I particularly enjoyed R. K. Sikoryak's mashup of Dilbert and Herman Melville's "Bartleby The Scrivener".  Maybe next year, Marvel will pitch in as well.
