De Beers was basically formed by an English colonialist (Cecil John Rhodes). He controlled a company which basically owned a country (http://en.wikipedia.org/wiki/British_South_Africa_Company).
He also had his own private army and tried to overthrow a sovereign government (http://en.wikipedia.org/wiki/Jameson_Raid).
One of the aims of the Rhodes scholarship is Anglicization. A person who did not study in English cannot apply (even though he is fluent).
Until recently they also excluded women.
In any cases, the legacy of Rhodes is despicable - even if he left behind a scholarship program. His creation of the state of Zimbabwe (with two different ethnic groups) results in problems to this day.
I don't think I was suggesting that it did.
