X is appropriate symbolically on a number of levels. I'm sure what Musk has in mind is to put his mark on Twitter like a dog marking his territory on every fire hydrant.
It's Musk's mark, which historically has been the symbol put on paper by every illiterate that was unable to sign his name.
And to X something out is to get rid of it.

P.S. There's another bit of apt symbolism that occurred to me when somebody posted that X is Musk's personal brand, and thus Musk has marked himself as the brand that, in many old commercials, got out-performed by the advertised brand. Yeah--
BRAND X
Brand X used to be so pervasive in many adverts that Marvel Comics paid tribute with a separate comic book line "Not Brand Echh".
