Court Blocks X Rival From Using Twitter Name, Allows 'Tweet'
A Delaware federal court ruled in a trademark dispute between Elon Musk's X and startup Operation Bluebird, granting X a preliminary injunction on the 'Twitter' name but denying it for 'tweet' and the Twitter bird logo, citing likely abandonment. Musk's own tweets about removing birds and the logo influenced the decision. Operation Bluebird, which rebranded to Tweet.app, cannot use 'Twitter.now' but may continue using 'tweet'. The startup, founded by lawyers, aims to acquire abandoned Twitter trademarks, charging $20 to reserve handles with over 172,000 requests. The case is ongoing, with a final verdict expected in November 2027, highlighting the impact of public statements on trademark protection and the legal battles over the Twitter brand.
- X loses trademark rights to 'Tweet' and the Twitter bird logo, but retains rights to 'Twitter'.
- Operation Bluebird is barred from using 'Twitter.now' but can use 'Tweet.app'.
- Preliminary ruling by a Delaware district court; final verdict expected in November 2027.

X Open Sources Its For You Ranking Algorithm
X has significantly expanded its open-source initiative by publishing the code behind its 'For You' timeline ranking algorithm on GitHub under the Apache-2.0 license via the xai-org organization. The release includes model configurations, filtering systems, and weighting parameters, making the codebase roughly 10-15 times larger than the 2023 release. According to TechCrunch, VP of Product Keith Coleman said the core ranking code can be run externally. The published weights reveal that likes carry a factor of 0.5, while replies, quotes and DMs are weighted ten times higher and link copies about 40 times higher; negative signals such as predicted reports, mutes and blocks are weighted much more heavily. X also launched an 'Under the Hood' transparency tool letting some users download labels applied to their accounts. The release comes after SpaceX acquired xAI, making X a subsidiary of SpaceX.
- X published the core code of its 'For You' ranking algorithm under Apache 2.0 on GitHub via the xai-org organization.
