Serious question, though I don't know if anyone here will necessarily know the answer.
I've heard rumors that Shalom Mordechei Rubashkin maintains a distance to the mainstream Chabad community because he feels slighted (or some sort of hard feelings) because Chabad didn't do much to get him released (although Boyarski of Aleph Institute is a Lubabvitcher and IINM he was deeply involved).
Is there any truth to that rumor?
It's clear looking back that the biggest factor (al pi derech hateva) in his release was Alan Dershowitz through R Tzvi Boyarski and the Aleph Institute, which is an "official" Chabad organization.
I personally know of numerous Shluchim who were instrumental in getting senators and extremely high profile people to sign letters of support and get eyes on his case even though it did cause blow back from their communities.
And "official Chabad" celebrated him at the Kinus banquet, and for obvious reasons not everyone was thrilled about that.
As for communal support, his name was mentioned at every farbrengen, public and private, that I went to for about a decade.
So, quite frankly, there is no truth to the "Chabad didn't do much" part of the rumor, though as for his feelings, that you would need to ask him.
