Also in this case the relation between bank and government is more tight than normal. It seems these organizations got a free (or easier to open?) bank account from Citi via the government.

Which potentially made it easier to not just stop subsidies from going to the organizations (DOGE style), but also to freeze these accounts.

So the lesson here is: pick your Uncle Jim wisely. Don't trust the hand that feeds you. Brush the gifted horse mouth?
