There is not need for an argument, everyone have their own belief so we don't need to force anyone to do airdrop or not.
Their are so many airdrop I am participating on currently and I am waiting for the mainnet so that I can ewrn from the coins i have mined which is one of the ways to earn from the market. Airdrops are forms of doing little task and getting rewarded.
We need to be prepared and be ready to take part in some good airdrop if we want to make money in the cryptocurrency space.
