I feel inclined to disagree with you again... nothing personal, but I think I should point out that they are "giving it to charity", and using it to acquire users...
It was just bad wording on my part. What I tried to say was that there's a difference between giving $150k to a charity outright and donating money on behalf of the users who refer more users.
SwipeGood is hoping that many people will make the same mistake you made. It is a savvy business move that lines up very well with their business model of supporting charities.
