It is meaningfully different: with the glass example the company can take concrete action and get back into compliance, and no longer have ongoing issues.

With any website (hackernews included) the only way they can actually completely prevent there from being copyrighted content in the comments that they host and publish is to not offer the ability to comment at all.

Or just remove all the links from comments...

We don't really need to link something to express an opinion

BTW HN have to check anyway, if I post a link to an obscure video sharing platform containing copyrighted material, that's an infringement

Even if the domain is whitelisted, say github.com, I could host copyrighted material there

They simply don't do it and rely on users's good faith

The text of a comment itself is user generated content that can contain copyrighted material.

The law regulates linked content

Web sites are already responsible for copyright infringements committed by their users
