As long as a program doesn't accidently serve Kitniyot, they'll survive.
Video no longer available, but Red Heifer accidently used Kitniyot splenda, and a women started throwing food and plates at the waiters.
Video is circulating on WhatsApp and another one of someone trying to calm her down, while a male (possibly her husband) is agreeing that her behavior is not OK, but it is also not OK to serve him kitniyot.
My guess is that the excessive reaction is related to Sholom Bayis arguments over participating in the program.
However, this fiasco just goes to show what is pretty obvious, that the vast majority of people participating in these programs don’t have Kashrus on top of their priority list. It’s more like a checkbox item.
