I've never seen the motivation behind buying Twitter to have been revenue, or free speech for that matter. Elon wanted a unique content source to train LLMs on and he got it. Whether that proves out as a good training dataset is still up in the air, but I can't imagine he cared about Twitter revenue.
This is not even intended for the LLM training use case. it is an afterthought use case. He installed a president who he can use. Twitter acquisition helped him achieve this.
Oh sorry, no I meant them shoving Biden into the candidacy despite clear health issues, shutting down any primary challenge, and swapping Harris in late in the game when it was abundantly clear Biden's health was a problem.
