I think I understand your point but the funnier response to this question is that actually sometimes it is:

To your narrow point, it's very obvious that Musk influences the bot to share his views. For example,

If your claim is that somehow I should not be concerned about Elon's politics with regards to the model itself, then this seems wrong.
Anyway, to the broader point of whether or not the we can avoid discussion about the Musk's politics and talk about the politics of the model as if it were independent of him, this also seems difficult. It is impossible to ignore because the man has made himself the face of every one of his companies and is an obviously political figure unlike any other company and has politics that are definitely characterized as more radical. This makes the political component basically impossible to ignore unlike any other company.

Well since Xi Jinping isn't tweeting his political opinions, he surely doesn't have any and is just a big friendly panda bear!
I'm not sure this is true; Xi Jinping probably has political opinions
