Each company has different funds to start their service, and promotions so they are free to choose how they run their promotions (with or without Escrow; manage promotions by themselves or hire managers).
I am fine with it. There is nothing wrong if a small (but legit) start-up run their campaigns by their own accounts and don't use Escrow. It's their company, campaign and fund, why they have to use Escrow?
BUT:
It is not good to see a campaign thread created as a self-moderated one, especially if it comes from lower rank accounts (without management history).
