are being pushed away FTL but they're not actually 'moving' FTL. They couldn't travel that fast towards us, or indeed towards anything.
it is kind like saying that because all stones fall down, one can't fly or jump. Like stone falling down, space expansion (cooling down) is an entropy increasing process. What we know is that any entropy increasing process can be reversed by applying energy (which gets obtained by even more increasing of entropy somewhere else).
