Do they not understand that designers, and especially publishers, have projects that go on and need to still be editable for years and years? I have dozens of books on backlist from past decades with type 1 fonts. Some day I might want to do another printing run, in which case I need to be able to open them and edit the copyright page and fix typos and so on. Preferably when I do this I don't discover that the whole thing needs to be retypeset. Graphic designers must exist in the same position.
Thank God we use TeX/groff and not InDesign.
