I remember that, but what does this mean? What was the kovod Lubavitch issues mean? And it is weird to write that...
From what I hear, there was an issue of the owner of the urgent care center originally contracted to do the testing, having a track record of causing problems to some Chabad house.
I have no first or second hand knowledge of those allegations.
So in essence, what is meant here by kovod Lubavitch seems to be self-respect and dignity not to feed the hand that slaps you. Not to be confused with Kiddush Shem Lubavitch which is a different issue.
