I read about 80% of the huge threads above and didn't see this
mentioned, but here's a recent court case dealing with a similar
topic.

And of course there's the infamous DECSS encryption-link fight.. one

And another here (equally infamous 2600 magazine hyperlink Froohaha).

Bottom line, currently it doesn't appear to be illegal to link to
other information on the web. It's a web, not a filament. If it were
to become illegal, the web as we know it would vanish.
That being said, it's generally rude to link to someone else's content
without at least attribution. And if requested to remove it, rude to
leave it up. But not litigable (well, I spose 'bout anything is
litigable. Freedom isn't free, you know.. )
Now of course, sometimes you WANT to be rude...
