I am not a security expert though, and I might be missing out on something.
The responsibility of GitLab and GitHub is also not to judge if it's "more important" to protect the site owners' businesses or the people going to the sites.
If some sites are running malware, the site owners are responsible for fixing it and not harming the people using their sites, not GitLab or GitHub.
On the contrary if site owners could be harmed by the name of their sites being on such list on GitLab or GitHub, then GitLab or GitHub are responsible according to the DMCA.
So GitLab and GitHub are just acting on what they are held responsible for according to the law.
Disclaimer: I am working as a contractor for GitLab and I am not a lawyer. I took no part in GitLab's decision to censor the list and this is just my own opinion.
Nope. DCMA is about copyright, and we have not gotten to the point where someones URL is copyrighted.
> It criminalizes production and dissemination of technology, devices, or services intended to circumvent measures (commonly known as digital rights management or DRM) that control access to copyrighted works. It also criminalizes the act of circumventing an access control, whether or not there is actual infringement of copyright itself.
So no the DMCA is not just about copyright.
