I feel like that was true at some point in the past, but advances in digital communication probably move the cliff effect further away than the middle shown int he wikipedia article. Like digital has error code correction and data compression and all modern long-distance communication (like space probes, cell phones, or satellites) are digital now.
Analogue is best for DX (distant communication) because of the cliff effect, it’s better to have KSSH than having the signal drop completely.
