Being that Grok is Elon's project, I have an inclination to believe he's purposely exaggerating the propaganda behavior to troll users so that they can see the nefarious bias nature of AI chat bots and how they are designed to influence thinking. On the surface it is a useless evil contraption, but maybe that's the idea so that people become aware and can notice the more subtle manipulation in other AI chat bots. So many people just blindly trust AI, for them it's the next big thing that everyone is doing... Just like they blindly trusted computers when they first got on the internet and instantly got computer viruses, many people are falling into the trap. A lot of software is designed to take advantage of people and so many walk naively right into trouble. They need a few bad experiences to become more guarded. So maybe that's why Grok behaves the way it does. Just speculation.
