The answer is that people have completely different sets of beliefs of what is actually happening in the world as they believe whatever stories are circulating in their own echo chambers.
For example, in this case a whole lot of people believe that it's not still continuing. Their sources of news simply report that it's not continuing, so they believe it.
This is a common pattern these days. They (whoever "they" are) simply operate with a set of information that doesn't quite match with reality, but given that set of information, it makes sense.
