It turns out that maybe it wasn’t because according to a post by Twitter, it turns out that Dorsey’s account was hacked. This was based on a series of tweets sent from Dorsey’s account that seemed to contain a lot of hate speech that included racist comments and also threats. It was later revealed that the attack seemed to have originated from a source called Cloudhopper.

If you are unsure who they are, they were a company that Twitter had acquired a lot time ago to boost their SMS service, suggesting that these tweets could be sent from that service. Twitter seems to have reacted pretty quickly where about after 30 minutes from when the first tweet was made, the company deleted them.
According to Twitter, “The phone number associated with the account was compromised due to a security oversight by the mobile provider. This allowed an unauthorized person to compose and send tweets via text message from the phone number. That issue is now resolved.”
