I don't get how you are coming to the conclusion that this guy wasn't valuable? I know nothing about him but based on his website [1] he seems pretty accomplished:
- I started an agency called Ueno. I ran it for seven years before it was acquired by Twitter in 2021... - At Ueno we designed digital brands and experiences for companies like Airbnb, Apple, ESPN, Dropbox, Facebook, Google, NY Times, Oculus, PayPal, Uber, Venmo, Visa, Walmart, and many more - ...And let's not forget I was person of the year in Iceland in 2022
Also, Twitter was not almost bankrupt before Elon bought them, that is silly.
