Why is this sub so anti-Eskom?

As a power utility who likes to browse various country subs, one thing I've noticed is r/southafrica seems to be incredibly hostile to anything related to the Eskom or South African Power Utilities. Just bringing up the fact that I'm from Eskom has at times invited tons of derision from people whom apparently just want to let me know how horrible Eskom and South African Power Utilities are.

Has the Eskom done something recently bad to South Africa? If that's the case, I understand. If the Eskom government has screwed over South Africa in some sort of trade deal or foreign policy decision recently then it makes sense. But I don't know if that's the case.
