It's not quite clear yet how the plants make these sounds, but the scientists suspect it is a passive process linked to cavitation. This is when plants that are stressed pop air bubbles in their circulation system causing vibrations in the plant.

A situation the plants evolve specifically to avoid and signal to every other organism in ear shot that the culling is coming Isn’t that enough? My body bloats in a passive process after it stops functioning, I avoid that

  While your body would also make noises if someone cut your head off, it's not a process your body evolved to signal everything around it to run.

    Its what would happen anyway because its a precursor to more undermining of self-preservation

  Maybe if the article said other plants could hear or react to the screams. What good would such a warning do for plants who cannot flee or fight back?

    That article didn’t, there are others that suggest there are signals to stressors that nearby plants react to. Even so, I can’t fly away from a tiger or bear. That analogy coupled with seeing that everything that can move, tries to move, makes me think plants would if they could. Sea anemones are very rudimentary and blind systems, and even they uproot themselves and “swim” away in the sloppiest way imaginable when a starfish is detected. Plenty of plants were able to select for defense mechanisms before reproduction. I think all would given the option.

      You can't fly away from a tiger or a bear, but a human screaming as they are eaten by that one night inspire you to run or hide from something you see as a predator. Your feet are not literally rooted in the ground. Also you have ears capable of hearing the noise created by another human.

        And how does that alter my point, further described in the observation you didnt mention
