You give any idiot a near complete monopoly and a dysfunctional regulatory environment (ICASA/Govt) and ANYONE can achieve the 'success' he had at Vodacom.
This 'success' came about by making supernormal profits at expense of the masses of South Africa. How could anyone sleep at night being the CEO whilst charging the masses a pay as you rate that that he did? Well he could do just that. The media in SA still regards him as a 'visionary'. They justified his extortionate rates, anticompetitive behaviour etc. If he was worth his salt he could heave gotten a job in a competitive market, except that he is not.
It was also at expense of making SA more competitive. His contribution to SA business was continued lethargy, price-manipulation, organised crime etc.
In short he is thug in a suit.
