Answer:
The advertisement is for mortgage products, not deposits. The Member FDIC isn't required at all, nor is it prohibited.
"No down payment" doesn't trigger additional disclosures (OSC 24(c)(1)1.)
The ad is in your bank, I think the viewer will know who the lender is if you customarily do these loans. But it makes no difference.
