Saying a threat is the opposite of forcing is definitely wrong.
But what is supposed threat about? We are talking about whether or not Google links to a website, which has nothing to do with that. Linking is purely voluntary and there is not even a contract.
Of course, at scale, financial incentives are still very important for businesses, but let's be clear about this. There are no goons or threat of goons involved.

1. Notice the use of isn't. I'm not a native English speaker but it still seems clear that you are reading something that isn't written.
2. The threat of being shunned is still a threat. Also there is something about abusive relationships where the abuser will say: I didn't force anyone, but everyone knows there would have been "consequences" if the victim didn't do what they were told.
