It was though. Xai publishes their system prompts, and here's the commit that fixed it (a one line removal): https://github.com/xai-org/grok-prompts/commit/c5de4a14feb50...
The timing in relation to the Grok 4 launch is highly suspect. It seems much more like a publicity stunt. (Any news is good news?)
But, besides that, if that prompt change unleashed the very extreme Hitler-tweeting and arguably worse horrors (it wasn't all "haha, I'm mechahitler"), it's a definite sign of some really bizarre fine tuning on the model itself.

I don’t recall where they published the bit of prompt that kept bringing up “white genocide” in South Africa at inopportune times.
