Mr. Musk may have successfully pushed Twitter's new name and logo, 'X', and even made the vanity domain x.com redirect to the social media website, but that's not to say, the Mathematical double-struck letter will fit the bill everywhere.

This could very well indicate resentment of Twitter employees, they were told to change name to X, they tried and it didn't work, so they did nothing else.
