Also not a lawyer, but links aren’t copyrighted and don’t require any special permission to share.

The reason why pirate bay and others got in trouble for sharing links is that they were linking to copyright infringing material.

Linking to the copyright holder where they publicly host content is not the same.

If they have want restricted access then they should configure restricted access. This is why Netflix makes you log in, etcetc
