As AIGC has impacted our society profoundly in the past years, ethical issues have received tremendous attention. The most urgent one is the AIGC copyright dilemma, which can immensely stifle the development of AIGC and greatly cost the entire society. Given the complexity of AIGC copyright governance and the fact that no perfect solution currently exists, previous work advocated copyleft on AI governance but without substantive analysis. In this paper, we take a step further to explore the feasibility of copyleft to alleviate the AIGC copyright dilemma. We conduct a mixed-methods study from two aspects: qualitatively, we use a formal what-if analysis to clarify the dilemma and provide case studies to show the feasibility of copyleft; quantitatively, we perform a carefully designed survey to find out how the public feels about copylefting AIGC. The key findings include: a) people generally perceive the dilemma, b) they prefer to use authorized AIGC under loose restriction, and c) they are positive to copyleft in AIGC and willing to use it in the future.

翻译：随着AIGC在过去数年间深刻影响社会，伦理问题受到极大关注。其中最为紧迫的是AIGC版权困境，其可能严重扼杀AIGC发展，并给整个社会带来巨大成本。鉴于AIGC版权治理的复杂性以及目前尚无完美解决方案的事实，先前研究主张在AI治理中引入copyleft，但缺乏实质性分析。本文进一步探索利用copyleft缓解AIGC版权困境的可行性，采用混合方法从两方面展开研究：定性方面，通过正式的假设分析厘清困境，并通过案例研究展示copyleft的可行性；定量方面，通过精心设计的问卷调查公众对AIGC采用copyleft的态度。主要发现包括：（a）公众普遍认知到该困境，（b）他们倾向于在宽松限制下使用经授权的AIGC，（c）他们对AIGC中的copyleft持积极态度，并愿意在未来使用。
