That would be true per our present understanding, but who knows how far technology can go?
To make a quantum entanglement transmission technology that was detectable by everyone in range (broadcast) you would have to quantum entangle every electron in (for instance) the galaxy.
Possible I suppose to some far advanced society but I think someone would have noticed that by now.
Or maybe they sell subscriptions. Imagine that! The advanced societies are Capitalist.
Dont tell the Dims. They think that futuristic societies are all Commies.
