X Corp. has filed a lawsuit against Operation Bluebird, a startup attempting to reclaim the "Twitter" brand, claiming that its recent rebranding does not signify abandonment of trademark rights. The suit argues that Twitter's legacy continues as users still refer to the service and its posts as "tweets." As of December 11, 2025, over four million users accessed the site via the "twitter.com" domain, reinforcing X Corp.'s assertion of ownership, thus intensifying the trademark dispute.
