This is very debatable. It's pretty clear that once you know that an opponent will fold the river immediately if he has nothing or a weak hand if you only grab for chips ( so basically you don't need to put anything at risk in the pot ) that you hold an advantage over him, making you win without showdown everytime on the river when he has a weak hand or nothing.
I guess it's a pretty thin line and it all comes down to each individual in particular. If you feel guilty about it OP, then you should tell him ( if you play with him again ) to just wait for when it's his turn to act and not take an action before hand. If you don't feel guilty, then don't tell him.
On the other side, he's an adult and if he plays this game, he should know the basics about it as this falls into the pretty standard beginner category.
Not to mention that this "weakness" of the player can harm you in other situations. For example, let's say you get to a river 3-handed ( you, the "weakness" player and another player, let's call him player A ). You're first to act, player A is second to act and the "weakness" player is last to act. You've missed your FD but plan to bluff the river. Player A has a mediocre holding at best ( ex: let's say second pair ). If the "weakness" player folds out of turn as soon as you grab for chips, then it makes it more likely for player A to look you up with second pair as he does not have to worry about another player to act behind him.
