Yeah but Mozilla Composer was begat by Netscape Composer, which was part of the push into "enterprise" and being a "collaboration suite" that jwz lists as the #2 cause for sinking of the Netscape ship:

Anyone who doesn't think the Netscape ship sank is probably too young to remember pre-Firefox (or too close to events to be objective); but the fact that the ship was salvaged from near the bottom of the ocean doesn't change the fact that it did sink.
