I’ll use the rock concert analogy.

Everyone can hear the music due to the huge speakers everywhere.

They can also hear the fans. When there are too many fans, it becomes hard for the band to make out what is being said (ever had “strong” signal but still can’t really do much?) by each individual fan. But one fan shouting back will not carry the same decibel level of noise as the numerous amount of speakers blasting out rock music.
