That's how charity works. Most don't do it to help the actual cause. They do it to feel better about themselves or for the perk of donating, in this case, the shader, shirt, and emblem. That being said, who cares why someone donated? As long as the money is being donated it all helps regardless of the amount. Slamming people for donating for the wrong reasons doesn't help the charity. It pushes people away from doing so because they feel like they're not doing it right. Donations are donations and they all help.
