Avira,
I don’t think you have to accept Reb Moshe’s view on Lubavitch (because (a) you can hold like someone else, and (b) you can say that Lubavitch has changed) –
But it is quite difficult to say that Reb Moshe didn’t have an extremely favorable view of Lubavitch and the Rebbe.
If you read the letters that I posted earlier (linked below), you’ll see that it’s much more than “lots of titles.”
He clearly supported the Rebbe and his activities very strongly, including various campaigns that Rav Shach and others strongly attacked.
