Taiwanese YouTuber Tsai A-ga (蔡阿嘎) triggered a boycott backed by 105,908 supporters after pairing a human painter's portrait with an AI-generated version in an 'AI vs. painter' poll, while the US, Taiwan, and China apply different thresholds for how much human creative input an AI image needs to qualify for copyright protection.
How Did Tsai A-ga's Poll Ignite the Conflict Between AI Images and Human Creators?
Taiwanese YouTuber Tsai A-ga (蔡阿嘎) set off the dispute by placing a Japanese street painter's portrait of his children next to an AI-generated version and asking followers to vote on which was betterCITE:E1. The comparison drew criticism for disregarding the human artist's original work, and a public response from Tsai A-ga's side failed to defuse the backlashCITE:E1. Japanese media subsequently picked up the story, describing the act of pitting the children's portrait against an AI copy as "too rude"CITE:E2. As the controversy spread, an online boycott petition gathered support from 105,908 people, and several brands that had partnered with Tsai A-ga were drawn into the falloutCITE:E3.
How Do Copyright Laws in the US, Taiwan, and China Define Protection for AI-Generated Images?
The US, Taiwan, and China all tie copyright protection to the degree of human creative input, though they draw that line differentlyCITE:E4CITE:E5CITE:E7. The US Copyright Office holds that content generated purely by AI, without identifiable human creative expression, is generally not eligible for copyright protectionCITE:E4. Taiwan's Intellectual Property Office (經濟部智慧財產局) takes a similar position: output produced by AI running independently, with a human merely issuing a simple instruction, does not qualify for protection, but works that reflect human creative selection and arrangement may have protectable spaceCITE:E5. China's Beijing Internet Court reached a more permissive conclusion in the "Spring Breeze Brings Tenderness" case, ruling that an AI-generated image can be copyrighted if the user invested sufficient intellectual labor in designing prompts and adjusting parametersCITE:E7.
What Legal Avenues Do Human Creators and Rights Holders Have to Protect Themselves?
Rights holders currently rely on two distinct mechanisms: the European Union's opt-out right and the music industry's opt-in licensing dealsCITE:E8CITE:E9. Under the EU AI Act, rights holders are granted the right to opt out of having their works used to train AI systemsCITE:E8. In the music industry, a commercial opt-in model has emerged instead, exemplified by Universal Music Group (UMG) partnering with AI music company Udio so that rights holders proactively license their works for AI useCITE:E9.
Why Has AI Training Data Licensing Become the Central Focus in 2026?
Entering 2026, industry attention has turned to the legality and licensing of AI training data, positioning it as the next major focus in copyright debates over generative AICITE:E6.
What This Means: The Tsai A-ga dispute shows how a single AI-versus-human comparison escalated into a boycott involving 105,908 supportersCITE:E3, even as the US, Taiwan, and China have not converged on one standard for when an AI image deserves protection — Beijing's Internet Court accepts a lower bar tied to intellectual labor in prompt designCITE:E7, while the US Copyright Office and Taiwan's IP Office require identifiable human creative expressionCITE:E4CITE:E5. The protective tools available to rights holders remain split between the EU's reactive opt-out rightCITE:E8 and the music industry's proactive opt-in deals such as the UMG-Udio partnershipCITE:E9, and attention is now shifting toward the legality of the training data itselfCITE:E6.
Author's Take・EffectStory 編輯部
The Tsai A-ga case matters less as a viral scandal than as a stress test of how far apart the world's copyright regimes still are. The US Copyright Office and Taiwan's IP Office both require identifiable human creative expression before an AI image qualifies for protection, while Beijing's Internet Court accepts a lower threshold — sufficient intellectual labor in prompt design and parameter adjustment. That gap means the same AI-generated image could be protected in China and unprotected in the US or Taiwan. On the enforcement side, the EU's opt-out right is a passive backstop, whereas the UMG-Udio opt-in deal shows rights holders can also negotiate proactively. The metric worth watching next is whether opt-in licensing models like UMG-Udio expand from music into visual art, which would signal that image rights holders are moving from defense to negotiation.
