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.
