So.... is this just like a really dumb cost-cutting measure to stop paying fees for the twitter domain/brand name or something, since he already owns the name "X"?
Nope, it's literally nothing more than the fact that Musk, like the cringey edgelord that he is, thinks the letter X is the coolest. He'll be painting go-faster stripes on Twitter next. Or the X logo will be on fire or something.
