They probably mean there is only a small amount of groups left that aren't ripping CR's translation, for CR-licensed animes, and releasing in pace with Japan. There are still fansubbers who take their time to work on something, but I suspect this lack of exposure, or of momentum if you prefer, makes it harder for them (there are fewer people interested in helping).
