"If you’re borrowing inspiration from any copyrighted material, even if it seems clear to you that your use is transformational, you’re in danger. If your use is commercial and/or potentially objectionable, seek permission (though there’s no guarantee it’ll be granted) or be prepared to defend yourself in court. Anyone can file a lawsuit and the costs of defending yourself against a claim are high, regardless of how strong your case is. Combined with vague standards, the result is a chilling effect for every independent artist hoping to build upon or reference copyrighted works."
