To always ask
You make a good point except for one thing. Lubavitchers make a yearly Siyum on Rambam but that doesn’t mean that they” learn” Rambam. What I mean is they turn the pages but since they reject many of Rambam’s fundamental principles it’s not called learning. Menace Friedman rejects Rambam’s 3rd principle of faith that G-d is incorporeal and has no human attributes by stating that He needs us more than we need Him. And Rambam gave clear-cut criteria for Moshiach which Chabad rejects because it refutes their ridiculous claim that Schneerson is Moshiach.
