This is a vulnerability in Twitter's verification policy that Twitter refuses to fix. Originally, verification was supposed to mean "this person is who they say they are". But once an account is verified, you can change the name/profile picture to someone else. So hackers get access to minor verified accounts, change the profile to match Elon, and then they have a "verified" Elon Musk account to scam with.
Twitter could fix this tomorrow by requiring that verification be tied to the name you got verified with, and if you do need to change your name you go through an (expedited) re-verification process. That doesn't seem like a lot to ask considering what "verification" is supposed to mean, and what (as evidenced by this article) users of the site take it to mean.
