What's "standoff" mean?

Native speaker’s answer

A "stand-off" is a deadlock between two or more parties over a dispute or conflict. It happens when both parties are equally powerful, and there is no obvious solution to the conflict. In the video, there is a stand-off between Facebook and the Australian government because they are both powerful, and neither one wants to give the other what they want. Ex: There was a stand-off between the police and the criminals. Ex: The workers union and the company were in a stand-off over higher salaries.
