The way I see it, the point of the lawsuit is that Fox’s dishonesty damaged Dominion’s business. Early on, Dominion made a statement along the lines of, we are not interested in a settlement where Fox writes us a check and doesn’t accept responsibility, which is the usual case when parties settle. "Neither party admits fault or will comment further.” That sort of thing.
Obviously, if Fox is coming with a gigantic financial offer, Dominion will consider it. But if part of the deal is that Fox gets to say “we do not admit that we knowingly gave a platform to defamatory content,” then those allegations continue to persist without retraction, and the financial settlement would need to be unprecedentedly huge for Dominion to accept it.
I'm assuming Dominion wants Fox to say, loudly and publicly, “it was all made up; none of it has a basis in truth; they were lies when they were first spoken, they continued to be lies when we repeated, and platformed them and they continue to be lies now; and we will make sure our audience knows this.” Fox doesn’t want to do that, which is why proceedings are still moving forward. The fact that Dominion agreed to a slight delay to listen to the offer doesn’t mean their position has changed. It could be an opportunity for them to restate their expected terms. It could also be a matter of strategy — the size of the offer tells Dominion how worried Fox is about the outcome, which is useful information even if there’s no plan to accept.
