Elon Musk's X(formerly Twitter) is now taking its final steps to eliminate the functionality they had added previously to include pronouns on the profiles altogether.

It was way back in 2021 that Twitter had announced a plan that would allow users to include their preferred pronouns on their profiles, partly as part of a broader industry shift to make way for greater representation in social apps.
In short, Twitter has relaxed its pronoun policy-one which took effect also in eliminating the policy that explicitly bars deadnaming, or calling transgender people by another former name, as well as the willful misgendering of trans users.

The update has apparently been hailed a major success among LGBTQ+ users. But as of a new note on the back-end code of the app, now it is eradicating every reference to pronouns from its databases outright.
Which, given Musk's earlier statements on the matter, isn't surprising, but it is another anti-progressive move that's unlikely to make the platform more attractive to key ad partners.

But in any case, to clarify, that ability to show your preferred pronouns was never available to all users, as Twitter had been working on the option when the Elon takeover happened. So it was never actually released, as such, but some users did have the ability and that was what was intended to be rolled out more broadly at Twitter.

But now, it's apparently disappearing, as a quelling of Musk's personal opinion about what pronouns are.
Which, in Elon's book, is "woke ideology," but even allowing people to decide how they're represented seems like less contentious of that particular contention.
Either way, it is gone, and I wouldn't anticipate X will begin rolling out an updated version of the same.

Unless it has to. Last month, X was forced to change its deadnaming policies in Brazil, mainly due to a court order, which X is said to be contesting now.

Perhaps, if other regions do so, too, X would be forced to do so anyway; outside of that, though, I don't see Elon letting such happen.
