No doubt they are trying to stop its use in other areas such as seed dressings - if these are equally damaging??? If you are going to stop its use in applications where it is causing death to 'friendly' insects, then it needs to be all those uses to reverse the downward spiral of insect numbers.
But you obviously know far more about it than the scientists, so carry on.
