One thing I should state immediately is that I think that Ogg Vorbis is great: it's cool technology doing all the right things in the right way. So my doubts about this campaign have nothing to do with any weaknesses in Ogg. It's just that I wonder whether this is really something the free software world should be expending much energy on when there are other more pressing problems. Whereas DRM and software patents, for example, are manifestly and unequivocally bad for free software (and indeed for everyone), that doesn't seem to be true for the MP3 format.
