What makes it illegal to develop software that will bypass computer codes on the copyrighted material?

Developing software that bypasses computer codes on copyrighted material is illegal primarily due to copyright law, which protects the rights of creators and owners of original works. This includes provisions like the Digital Millennium Copyright Act (DMCA) in the United States, which prohibits the circumvention of digital rights management (DRM) technologies. Such actions undermine the protection of intellectual property and can lead to significant financial and reputational harm to the copyright holders. Consequently, creating or distributing tools that facilitate this bypassing is considered a violation of these laws.
