I liken Airdrop as a tester of a food product. If we want to buy a food, of course we need to taste the food to ensure that the food we buy is truly delicious. So too did the development team think. The development team provides a number of coins for free in airdrop with the hope that if the coin is useful and gets the public's trust, the coin will be bought a lot. This is what I captured from the developers' aim to hold airdrop.
