I think there may be a useful distinction here between prior restraint and compelled speech. If you post the statement "we have not received a gagged warrant since January 3 2023" and you receive a gagged warrant on January 4 2023, does the government really have the power to compel you to post the statement "we have not received a gagged warrant since January 5 2023" the next day? You don't even have to take down the January 3 canary; just leave it up long enough that people get suspicious that you haven't updated it.
