Every "charity" that I've looked into was actually a money-making enterprise disguised as a benevolent one. Some of them have exposed publically, like Easter Seals, Boy's Home, and the Clinton Foundation. In these organizations, a small proportion of the collected money actually goes to the advertised cause, but that's just for show.
To add to the list, a guy was staying at my house for a while who previously worked for Make A Wish Foundation. He talked like almost 100% of the money went to those who collect it. In fact, while he was at the house, he was collecting for the Fire Department's book on fire safety for children. In reality, there was no such book.
Thus, anytime I hear the word "charity", I think "rip-off".
If you want to give money, find the recipient yourself and give directly. If you must use a big organization to move your funds, make sure it's ran by someone you trust.
Regarding the charity the article is about, I don't know anything. But, to me, it smells funny.
