One would think, however, under the proposed legislation, even returning links requires payment to the media organization.
That is not what is happening here (at least not for Facebook). This is just about links.
That is what the legislation requires and is simply a money grab. Further, to prevent people from just posting links to non-Australian sites in response, the law prevents that as well.
This is a direct response to how the law works. They would be required to pay even for links to the other sites. They decided it was not worth it.
No, they would have to pay for those as well. In fact, they cannot even allow international news links.
