The former is legal, the thinking goes, because the government cannot force you to continue posting a warrant canary. Nobody can say, “you have this on your web site saying you have never received a warrant; here’s a warrant, and by the way, you must also continue saying (now lying) that you have never received a warrant.” The government can tell you to /stop/ posting a daily or weekly notice. It can say “here’s a warrant; you may not tell anyone you have received this.” In that case, you would be lying to say you had /not/ received it, and discussing whether you have received it or not received it at all can be prohibited. In which case, you would be obligated to remove or cease updating any statements related to a warrant.
