As a graphic designer, I knew at a glance that nobody was paid to make that stupid "x".
If a client as big as Twitter asked me for an X logo I'd be so fucking depressed. It would be such a pain to make a proper logo like that without looking exactly like a dozen other ones, because it's hack and has been done to death.
The X everything app is literally some high school composition notebook doodle shit Elon has been clinging to for over 20 years. He's like the dad from the movie Holes that thinks he's a great inventor, but just keeps catching the house on fire and stinking up the place.
