I imagine that leading up to the election, they don’t want to show a pattern of unsubstantiated false election claims, since that can be used as evidence if later there is a claim by a host or guest which names a company directly that can be used in a lawsuit.

If such a lawsuit were to happen, they can point to this instance and claim that they tried their hardest to stop the unsubstantiated claims (even cutting off the former president), and it’s not a systemic issue in the network.
