If this is about that makata clown though - it's irrelevant. He didn't invent it. He didn't patent it. He didn't implement it. Why should he benefit from it?
Because he initiated it and was credited with it within Vodacom and they agreed, in writing, to compensate him for it including a share of proceeds. It's their own damn fault especially as they allowed so much time to elapse and frustrated the process and negotiated in bad faith resulting in where they are now. I'm sure they've updated their policies and employment contracts.
