The Twitch streamer posted a new YouTube video celebrating the court's decision, calling herself the "Queen of Fair Use" and saying she had "saved react content on the internet for everyone." Her comments came just days after a U.S. court ruled that her use of Klein's video was protected under fair use. While Denims is celebrating the result, Ethan Klein has already confirmed that he is appealing the decision, meaning the legal battle is not over yet.Denims celebrates court victory over Ethan Klein and calls herself the "Queen of Fair Use"Denims wasted no time reacting after the court ruled in her favor. In a new YouTube video, she celebrated the decision and proudly called herself the "Queen of Fair Use."She also claimed that she had "saved react content on the internet for everyone," suggesting that the ruling could help protect creators who make reaction videos in the future.The lawsuit began last year when Ethan Klein sued Denims, along with Twitch streamers Frogan and Kaceytron. Klein argued that the creators had used his YouTube video, Content Nuke – Hasan Piker, during their livestreams without permission. According to him, their broadcasts showed too much of his original video and hurt the performance of his content.However, on July 1, 2026, the court ruled in Denims' favor. The judge decided that her use of Klein's video was protected under fair use, which allows copyrighted material to be used in certain situations, such as commentary, criticism, or reactions.The judge found that three of the four fair use factors supported Denims' defense and granted her Motion for Judgment on the Pleadings, bringing this stage of the lawsuit to an end in her favor.Ethan Klein disagrees with the ruling and has already filed an appealAlthough Denims celebrated the outcome, Ethan Klein made it clear that he does not agree with the court's decision.In an Instagram Story, Klein said he believes the ruling is incorrect. He argued that it could allow people to watch almost an entire newly released video during a livestream while adding only a few comments and still claim fair use protection.Klein also said the decision does not match another copyright ruling involving H3 snark moderators that came from the same court district. Because of that, he said he is "extremely confident" that a higher court will overturn the decision.He confirmed that the appeal process has already started. An appeal does not change the current ruling. Instead, it asks a higher court to review the case and decide whether the earlier decision should stay the same or be changed.For now, Denims has won this stage of the copyright lawsuit and is celebrating the result with her supporters. However, Ethan Klein's appeal means the legal fight is still ongoing. The final outcome could become an important moment for future copyright and reaction content cases, as many creators will be watching to see what happens next.
