U.S. Senators Marsha Blackburn and Peter Welch have demanded that ByteDance immediately disable its newly released AI video generator, Seedance 2.0, accusing the company of enabling widespread theft of American creative works and calling the tool “the most glaring example of copyright infringement from a ByteDance product to date.” The bipartisan letter, addressed to ByteDance CEO Liang Rubo, urged an immediate shutdown and removal of unlicensed material from the firm's training sets as a condition for continuing commercial ties with free-market economies.

The senators cited a string of viral examples that they say emerged within 24 hours of the model’s February 12 launch, including an AI-fabricated fight staged between Tom Cruise and Brad Pitt, an altered ending to Netflix’s Stranger Things and a digitally created clash between Superman and Thanos. They also highlighted a case in which the model reproduced a high-budget shot from the film F1 for roughly nine cents, saying Seedance 2.0 delivered a “near-exact copy” that bypassed the original production’s costs. According to the lawmakers, those incidents demonstrate Seedance 2.0 was released without licensing of source material or effective safeguards to prevent infringing outputs. [2][3]

Hollywood’s major players have joined the outcry. Netflix told ByteDance it “will not stand by and watch ByteDance treat our valued IP as free public domain clip art,” issuing demands that the company stop the unauthorised recreations of its shows. The Motion Picture Association has sent a cease-and-desist and accused Seedance 2.0 of reproducing copyrighted characters and elements across studio catalogues, while actors’ union SAG-AFTRA and groups representing creators have warned that unauthorised use of likenesses and voices undermines performers’ livelihoods. The MPA has asked ByteDance for detailed disclosures about the tool and its training data. [3][4][5][7]

ByteDance has said it respects intellectual property rights and vowed to reinforce safeguards on Seedance 2.0, describing steps to prevent unauthorised use of copyrighted material and likenesses. The senators, however, dismissed those assurances as a “delay tactic,” arguing that promises to “strengthen current safeguards” are insufficient and do not address what they describe as the model’s distribution pre-loaded with unlicensed content.

The letter frames Seedance 2.0 within a broader pattern of concerns about Chinese technology and intellectual property, noting prior U.S. government warnings about online piracy and forced transfers. Blackburn and Welch tied the release to longstanding trade and IP frictions, saying the scale of alleged infringement heightens the national-security and economic implications of allowing such tools to operate unchecked. [2][4]

Industry lawyers and trade bodies have signalled potential litigation. The MPA gave ByteDance a tight deadline to respond to its demands for information, underscoring the “massive litigation risk” the senators warned about. Studios, unions and rights groups have mobilised legal and public-relations pressure that could result in coordinated suits or regulatory scrutiny if unlicensed uses continue. [4][5]

As of Tuesday afternoon, ByteDance and CEO Liang Rubo had not publicly agreed to the senators’ demand to shutter Seedance 2.0. With Hollywood, lawmakers and creators escalating their responses, the dispute now pits rapid AI development against established copyright protections, and sets up a test over how platforms must police generative tools that can replicate high-value creative works.
