At The Intercept, Glenn Greenwald lays out some of the most important principles for which the Clinton charitable foundation ostensibly stands (e.g., women's rights, LGBT rights and economic oppression). He then makes an overwhelming case that the Clinton principles are anathema to the despotic dictatorships "donating" to the Clinton Foundation.  Therefore, it follows (unless one believes that electing Hilary Clinton is so important that clear evidence that she is corrupt is irrelevant) that despotic regimes like Saudi Arabia are donating to the Clinton Foundation for reasons other than furthering the stated goals of the Foundation. So why are the despots shoveling tens of millions of dollars to the Clinton Foundation?  Clinton apologists try to redirect the discussion at this point, arguing that the Clinton Foundation has done some excellent charitable work.  Glenn Greenwald responds:

That the Clinton Foundation has done some good work is beyond dispute. But that fact has exactly nothing to do with the profound ethical problems and corruption threats raised by the way its funds have been raised. Hillary Clinton was America’s chief diplomat, and tyrannical regimes such as the Saudis and Qataris jointly donated tens of millions of dollars to an organization run by her family and operated in its name, one whose works has been a prominent feature of her public persona. That extremely valuable opportunity to curry favor with the Clintons, and to secure access to them, continues as she runs for president. . . . .
