Hi @19henne as you can see from the moderator's reply King do not wish to share with us why they do this. Generally the reason King do anything in the game is because it has proven to be profitable in their tests. So after tweaking a level so that the keys drop so late that players will have to spend gold or money for extra moves, if then a lot of players do just that - spend the gold or money - they will keep the level as it is. If most player do the opposite - stop playing and stay stuck - they will probably increase the moves for such levels. This is just a guess of course. King don't share their reasoning with us.
