Yeah, I really could not understand the motivation behind that. Why throw away such a valuable brand? I mean the name was even a clever play on words that also gave them a cute bird icon/mascot.
"Twitter", with that bird logo is just a slam dunk, that's solid gold branding... It's insane to randomly "go a different direction" and then land at "X". If I was their brand coordinator or director of marketing when they made that change, I'd resign then and there.
Changing their name to "X" was essentially lighting 20% of their assets on fire on day 1.
It's going to be so easy for him to turn that x into a swastika in a couple of years though. Its what's known in tech circles as IED "iterative evil design"
He is really really dumb person, so it is not surprising he does stupid stuff. Look at cybershit, tesla robot (driven by people remotely), anything he did last year... He is fucking dumb idiot.
