That's really not clear at all.

I earnestly can't anticipate what specific information-diet someone could have where they would so strongly assume that Google Deepmind (of all the various AI companies) is a clear and sole foil to Grok that they would assume anyone who didn't share that perspective to be feigning ignorance in bad faith.

Where-ever you're having these discussions where it's entirely unfamiliar to me (and evidently others). (I don't say this with scorn or malice!)

On the greater topic of "bias", it's kind of meaningless. There's correct answers and there are incorrect answers, and "bias" refers to some tendency away from an assumed default distribution. Randomly-generated strings might be the only "unbiased" response. This is really more a difficult epistemic question, and I'd prefer something that is biased towards what's most likely to be true (e.g. Wikipedia > someones Livejournal).

Given Grok has been intentionally made to generate text praising Hitler, and I have very very high confidence that Hitler actually sucks, I have very very low confidence in the ability for the Grok program to reliably generate text that's worth reading.
