I think the article gives more creedence to YCT than it merits.
Frankly I have never heard YCT ever mentioned in publically shul or in private conversations. ONCE when the Rabbat came out was even Avi Weiss mentioned.
I hear more about YCT here than I do anywhere else. I wonder if some are just pumping them up.
I do think YCT is to MO what Netueri Karta is to Charedism. Even the leaders have the same name WEISS
