No, the complaint is that they make a big point about only being pure technique, no faith, dogma, etc. Then they act like any other place. If they were honest about it from the get-go, then it wouldn't be worth mentioning.

Fwiw, not all Buddhist monasteries or organizations do anything like this. I've been to retreats at a Shambala center and at one of the monasteries in Thich Nhat Hanh's Plum Village network and they were very secular.
