I like the "formally" vs "formerly" suggesting Elon is never going to get away from Twitter in favor of X
One of his many children is trans, and she has disowned Elon for his terrible behavior. He doesn't respect her identity, pretends she is a stereotypical trans person (the right wing stereotype), and pretends he wasn't an absent father to her.
That seems depressing on her part. But I already assumed he would be a shitty father. With his behaviour online, I would assume he was a dead beat father.
