Once again you're full of assumptions. The mashgichim at POTM for example were all Chabad.
Here you go again using labels.
What does that mean? What does that say?
I happened to be walking back from תהלוכה with someone whose son was there for the first days. I asked him whether his son would eat there. He answered that he assumes he did eat there but would rather not ask, and that this son makes sure to go for Pesach to high-end sedorim, and eats wherever he goes. He said that he has another son who will just go wherever needed, and will eat just minimal things (hard boiled eggs, etc.) or take food along for himself. This story seems to indicate a negative correlation between emphasis on luxury and kashrus scrupulousness. I try to avoid assumptions, but life experience does indicate something.
