Ah, that explains it.

Anytime someone announces that they will invest X million into a public charity, always ask, over what period and under what conditions? This reminds me of how BP pledged $20 billion to help the Gulf states affected by the oil spill, but they didn't mention the tax break they got out it and how it was actually placed in an escrow account with conditions favorable to them.

I applaud his actions but question his timing and motivations.
