OK, so maybe Tom Warren is not the most likable guy, or not one to defuse a controversy that can lead more people to his website.

But I think it is technically correct:

• There is both 𝕏 and 𝕩, not sure which one looks closer to the "formerly-called-Twitter" one, but they do look really close
• They do follow a way of writing that predates the X11 logo, I wouldn't be surprised if the X11 logo itself was inspired by that too
• The glyphs appear just like that as part of the default Unicode typeface I'm using on my phone right now

I think the part we should take from this, is "Elon just wrote an x in a '1337 way', and called it a logo".
