He said ''apartheid Eskom'', not ''apartheid'' and the good 'ol days. His next post greatly expanded on what ''apartheid Eskom'' meant. I knew immediately what he meant as I have said something similar in the past in another thread. You and the rest just saw ''apartheid'' and immediately jumped to conclusions.
Apartheid-era Eskom - Eskom free of political meddling; Eskom not used to meet political targets; Eskom not used to enrich cadres; Eskom run by technocrats and not (corrupt) politicians and accountants.
Current Eskom - Eskom run by people deployed on political merits that do not understand the energy industry; Eskom used to siphon money; Eskom used to meet political goals (free electricity, transformation, etc).
Until the ANC stops using Eskom as their own personal playground it will never be turned around. That is what he meant because the NP government didn't do that and it functioned at 100% as a result.
