To get even more pedantic: I wouldn't say Cangjie or Dayi inputs are an "alphabet", and a sizeable number of users use those. They're certainly a way of inputting characters; and a method of looking at how glyphs can be broken down (one by stroke order, one by shape), but for it to be an alphabet there must be a rough phoneme mapping AFAICT; which there isn't. (but yes, the majority seems to use phonetic/alphabetic input methods, i.e. pinyin or zhuyin.)
