Well, in my experience, calling it Twitter or any variation helps people stay in negation about the fact that Twitter is dead, and calling it x makes people more likely to open their eyes and delete their account, and losing users is what really hurts musk. I already helped all the people from my close friends circle to move out from that shit.
I guess both actions have ups and downs.
To me, calling it Twitter reminds me of the shitty shit Twitter has ever been. I never liked the thing. I vividly remember when BBC started quoting random tweets - it made me a little sick. Then all news outlets followed suit.
And if Elon hates it that people call it Twitter, then even better!
