Cs, from an outsider perspective, there has been a change in chabad after the Lubavitcher rebbe passed away. The tzfas-niks weren’t an issue before he passed away, and tznius was a ton better in crown heights. I don’t think you can deny that modern elements, brought in by the large number of recent BTs and gerim, have affected chabad culture – just go out and look at what the younger generation does.
Fanaticism and modernity are flip sides of the same coin – the void of stable leadership. They need a new rebbe; it’s not very complicated.
