there was a tendancy in some quarters to forget that the ATC is a supporting organisation to the RAF and the accompanying attitude of "why doesn't RAF (insert name here) do more for us?".
Actually, it is the other way round. the ATC is supported by the RAF but there is no requirement for the ATC to give anything back to the parent service (inventory excepted.)
However, the Air Cadets are seen as a worthwhile investment in much the same way that university bursaries are seen as a worthwhile investment in that both systems help to provide worthy candidates for the royal Airforce, even if that is not their primary goal.
To demand that the RAF give more support, though, is arrogant. Granted, it would be nice but everybody has resource limitations and that needs to be taken into consideration. Besides, the RAF could be far more obstructive if they chose to be, so it is best not to rock the boat
