Exactly social media sites are not broadcasters, why should they pay to provide a link to forward users to a broadcasters website.
I would understand if a social media site wanted to summarize a news article for it’s users to keep its users on its site. This would theoretically make a social media site a broadcaster.
Its like asking a convince store to pay a Canadian News Tax because they provide newspapers inside their store.
This would theoretically make a social media site a broadcaster.
Not without a license allowing them to transmit radio and/or TV signals. Of which there would be no reason for Facebook to have.
It might make them a news agency, but news agencies are not subject to broadcasting regulations. Only broadcasters are subject to broadcasting regulations. The CBC is a broadcaster. Facebook is not.
