I do not know what they give to new projects, but for us it's not a bad opportunity to earn a few coins. Some of them show good growth
Airdrop is giving a small type of advertising that it gives free coins to the people who will join their airdrop.
This is a way to implement their project and let the people know that there is an upcoming project and so they get attention through airdrop making.
The article is correct that it has nothing to do with showing real project. They are only making their token popular by giving out free fractions.
