Maybe, but in this instance the trickle down is personal... the people who benefit (franchisees) would be trickling the benefits down to people they know -- their employees. I think the calculus ends up being different when you are giving benefits down to people you know (as opposed to the more nebulous trickle down). McDonalds could also dictate how any rent deferral was handled.

In reality this is the effect of trickle up economics. Ie the upper class relies on extracting wealth from the bottom mostly through labor. This is a fight for their own survival.
