Gates needs to be investigated to determine what his true motives are. It does make you wonder.
At that level it is almost certainly money. Several big name corporations gave the Boy Scouts a bunch of money for a few years, then said they wouldn’t give any more unless they changed their policy on homosexuals.
This makes perfect sense to people like Gates, who understand big corporations and relate to them, not ordinary people. They always tell themselves that they can do “so much good” with all that money, but the truth is that it is a devil’s deal: sell your soul for wealth, but when the contract runs its course, you lose your soul.
