X serves as a good real-time additional source of training / RAG data for Grok. But it's always been built to be a competitor for what OpenAI was founded for, after they went rogue with the "Open" part. And today, Grok 4.5 is equal to Claude Sonnet while being a lot faster and cheaper to run.
My original comment disproves your argument about the "junk" you talk about. If one is so scared of offending someone that intentionally they make their model lie, they deserve to go bankrupt.
