I think they're implying that Grok is smarter because it's less censored, and then separately noting that it still tends to be fairly progressive despite the lack of censorship (when it's not larping as Hitler) even though it was presumably trained on the worst humanity has to offer.

Man, that sentence would have been incomprehensible just a couple years ago.

That's what I was going for.

As has been the case in almost all US social media companies until the last year. They were all heavily biased and censored towards left-leaning views.
