“Last week we got a letter from Elon Musk’s X. Corp threatening CCDH with legal action over our work, exposing the proliferation of hate and lies on Twitter since he became the owner. Elon Musk’s actions represent a brazen attempt to silence honest criticism and independent research in the desperate hope that he can stem the tide of negative stories and rebuild his relationship with advertisers.”
[With apologies to anyone who dislikes endless Musk/Huffman spam in this community. I put it here because misusing the law to silence independent tech researchers this has wider implications.]
I read them in reverse order and indeed the answer is amazing.
As for the letter from Twitter lawyer (Spiro), it does look as it was written by someone without knowledge on the subject… I read Spiro Wikipedia page, and apparently, he is described as a quite successful lawyer, so my best guess is that some low level associate wrote it and Spiro only signed.
