The dynamic and creative global internet of today exists partially because websites and online intermediaries are not held liable for content posted by their users. These legal protections allow internet access providers, content hosts, social networks, and others to support a robust online environment for free expression without worrying about potential liability for the material stored on or moving across their networks. Without them, services would be much less willing to accept user-generated content for fear of potential civil and criminal liability.

In both the U.S. and Europe, CDT advocates for ongoing liability protections for online intermediaries and seeks to find workable solutions to address issues around illegal content, hate speech, extremist content, and misinformation.
