Well it does appear as if there was a change in the intervening years between TOS and TNG, though we don't know why. Perhaps an attempt to save a culture went badly.
from memory in "The Paradise Syndrome" it seemed perfectly ok for the Enterprise crew to intervine to prevent a natural disaster in this case an asteriod collision. Yet in TNG's "Pen Pals" it wasn't ok.
