ByteDance’s AI Tool Faces U.S. Shutdown Over Viral Copyright Rows

• ByteDance’s Seedance 2.0 accused of viral copyright violations.
• Senators and Hollywood unite to demand its immediate shutdown.

On March 17, 2026, CoinDesk reported that U.S. Senators Marsha Blackburn of Tennessee and Peter Welch of Vermont sent a formal letter to ByteDance CEO Liang Rubo, demanding the immediate shutdown of the company’s AI video tool, Seedance 2.0. The senators accused the tool of violating copyright and intellectual property laws by creating unauthorized viral videos featuring celebrity likenesses, movie scenes, and popular franchises.

The senators highlighted specific examples of Seedance 2.0’s output, including a fabricated fight between actors Tom Cruise and Brad Pitt and an altered ending for the television show Stranger Things. They described the tool as posing a “direct threat to the American intellectual property system” and called it “the most glaring example of copyright infringement from a ByteDance product to date.” The letter emphasized that the model used unlicensed training material and lacked sufficient safeguards to prevent unlawful content.

The demand from lawmakers followed a swift backlash from Hollywood studios and industry groups. Disney issued a cease-and-desist letter accusing ByteDance of conducting a “virtual smash-and-grab” of its intellectual property. The Motion Picture Association (MPA) also expressed strong opposition, urging the platform to address what it described as blatant violations of IP protections.

ByteDance had planned to roll out Seedance 2.0 globally in mid-March but paused the release in response to mounting legal pressure. Media outlets reported that the company’s legal and engineering teams are now working to strengthen safeguards to block unauthorized content. Despite this, the senators dismissed the promised updates, describing them as “delay tactics.”

The controversy surrounding Seedance 2.0 has reignited broader concerns about China’s intellectual property practices. In their letter, the senators argued that ByteDance’s actions illustrate a broader unwillingness to comply with U.S. law and urged the company to take immediate corrective measures to protect American creative industries and intellectual property systems.
