I don't know the specifics of the proposal, but I imagine that HN would be safe, unless the blog post author got annoyed at making it to the front page. Your point, however, is a good one.

If linking to copyrighted material without permission counts as copyright infringement, then linking to anything, anywhere becomes a very dangerous act. It'd probably also hurt Twitter and Facebook badly (no more linking to viral videos or funny images).
