The reaction was total silence. The reasons for this are not difficult to understand. There is a tacit alliance between three powerful vested interests which have nothing to gain from talking about these things, and much to lose. All three might suffer if the value of what any one of them is doing was called into question. So the most effective defence against criticism is to ignore it.
Open debate is the last thing they want.
Languages are learnt. They cannot be taught. Learning a foreign language is a process of intensive observation which people have to do for the most part alone. Language students may conscientiously do the homework they are set and regularly study their course books. It will do them little good if they lack self-reliance and active curiosity.
