Unfortunately it is due to the stupidity of the general public. There was no rational reason to attack the Asian community in Canada for causing the "Wuhan" virus, yet it happened anyways (more in the states, but there were stories here). Similarly, identifying an outbreak on a Hutterite colony stigmatizes Hutterites. Saying an outbreak occurred in Brandon doesn't have the same effect, because a Brandon resident wandering around in public isn't as readily identifiable, otherwise I am sure people would crap on them too.
