I must say that the Gates Foundation investment philosophy makes sense to me. They could be activists divesting themselves of all evil companies, but where to start and when to stop and who decides in such a Red Guard approach? Gates Foundation suggests that they rule out only companies whose central profit model is repugnant to Bill and Melinda, such as tobacco stocks. If you don't like capitalism, you don't or should not much like Foundations either. The two go together like a high revving engine and the oil that keeps it from seizing. To run an economy or a foundation by moral rules would require a Mullah, or Saint Barbara. The goal in a capitalist economy is to make lots of money by legal means, externalize costs wherever possible, and then use a small percentage of the gains so made to clean up a small percentage of the messes so made. We call this a win/win situation and applaud the capitalist coming (for making the money) and going (for giving a tiny bit away to offset the mess). If you concentrate on the ever widening messes (environmental destruction, wealth inequality, plutocracy supplanting democracy), it can very depressing because on a certain analysis these messes are systemic, inherent in late stage capitalism, and well beyond the capacity or the will of Capitalist Foundations, their advocates and polite critics, to even discuss much less address. So, I say, make a bundle, invest for total return, give a little away, and let's not look deeper than that lest the whole stinking mess come to the attention of the general public, and destabilize the entire system, throwing us all out of work.
