I saw rumors of this a few weeks ago but didn't think anything of it. Is the domain changing too? Part of this the Comcast to Xfinity move, rebranding to drop association, I think. But Twitter's brand wasn't that bad so I don't know.
WTF did Elon even bring to PayPal when he merged with Confinity if he still has control over the x.com URL and name? It certainly wasn't competent leadership.
