On Thursday, Elon Musk’s social media platform, now known as X, won a legal battle to block a group called Operation Bluebird from launching a new app under the name "Twitter." The court ruled in favor of X, stating that Operation Bluebird was unlikely to prove that X had completely stopped using the name "Twitter." This decision is crucial because it relates to trademark law, which protects companies from having their brand names used by others without permission. Judge Colm Connolly explained that X still uses the name "Twitter" in its App Store listing. The first line of the listing, written in the same font size as the rest of the text, reads, “Welcome to X (formerly known as Twitter).” This simple addition was key in X’s legal argument. According to X’s legal director, Naser Baseer, the clause was deliberately added to help users who searched for the Twitter app—both within and outside the App Store—find the X app and understand that it is the same platform. This, the judge noted, helps maintain the connection between the old and new names. Legal evidence also supported X’s claim. Surveys showed that people still recognize "Twitter" as a well-known brand. Even though X has removed the name from its platform, the company continues to benefit from the reputation and goodwill that the original brand built. Judge Connolly wrote that X uses the association with Twitter in the App Store to strengthen its position, making it clear to users that what they once knew as Twitter is now X. The court also considered the redirect from twitter.com to x.com, which could further support X’s case. However, Judge Connolly did not yet need to make a ruling on this point. To prevent potential harm to X, the judge ruled that Operation Bluebird must be blocked from using the name "Twitter" until the legal dispute is resolved. This temporary block aims to protect X from any possible loss due to the unauthorized use of its former brand name.
