There are many cases of bad branding. Note Microsoft's habit of naming things without doing the simplest trademark search. I used to covet 3 letter domains. If I had a 1 letter domain I would want to use it. Musk was stuck on that name a long time ago, and it's a way to assert power over his platform and drive away people who won't play along with him but it is a real gift to Bluesky. People might not be so offended…
I don't disagree, but this is about *re*branding. Twitter was and is a globally iconic trademark, brand name, and has even entered the lexicon (tweeting, etc), and he flushed that for no obviously good reason. Worse he then replaced that branding with something unremarkable and generic. I can't think of a similar case at this scale, where SO MUCH was traded in for so little, without any external pressure to do so.
One is that Elon Musk was able to curry Donald Trump's favor by destroying Twitter and setting an example. If he gets enough political power out of it to justify the cost it might be rational.
Another is that Elon just was not thinking straight. Like having a midlife crisis, possibly complicated by a neurodivergence. Remember how he tried to back out of the deal when the price collapsed but faced a lot of "external pressure?" Plenty of people spend money on something stupid around age 50, he just has a lot more money than most of us.
