Yep, and not his first rodeo either. Remember the "Internet.org", a for-profit initiative that is part of Facebook? Putting ".org" in something for-profit that tries to achieve monopoly is as dishonest as it gets...
If you read higher up in that wiki it lists all of the money the initiative has given away so far. I'm not sure why people think that the LLC doesn't give away money.
Even in that case, he and his family will for a long time have the political benefit of deciding how the money will be spent. And political advantages usually translate into economical advantages, so it can also be viewed as a scheme at some level.
Not exactly, I'm pretty sure Bill Gates is a nonprofit. However, there's a book called "No Such Thing as a Free Gift" about the social costs of letting our .00001% be the welfare providers for society. Pretty good if you're interested.
