It does not surprise me. The free Grok got worse since 4.0, they increasingly save money by not responding at all or only allowing one answer. Grok now defends the administration and billionaires.
The company seems to burn money like crazy. Everyone knows that "AI in space" and the downgrade to a moon trip after claiming for 15 years that Mars is just around the corner are marketing.
All AIs are toys and the coding promises are just a lie to string along investors. Unfortunately many of these are senile Star Trek watchers who buy into everything.
