I partly agree. However, if one project will include the buyers of the tokens in the airdrop then I think there would never be a problem. We all know that airdrop is now being used as a marketing strategy to generate awareness for the program as well as to build a sizable community which can be critical especially after the ICO phase of the project. As in anything in life, there will always be advantages and disadvantages and it is all up to the project's team to manage and balance all the issues and concerns. As for me, I would not be complaining to be receiving some airdrops from time to time.
