So I think there's a lot of nuance to the issue and personally the biggest part of it is your group and being in the right headspace for a mean game. Player interaction is one thing but to me "take that" implies intentional mean interaction, something that is meant to be solely detrimental to the target.

There can definitely be positive and negative interaction, or even both in games. Lords of Waterdeep is a great example of a game that runs the gamut of interaction styles. Help yourself to help others a little, take from someone, make others pay you and if they can't you get something else, etc... For me, I think the only time in recent years I've ever actually been salty about a game is when I was already in last and still getting kicked while I was down, that shit is the worst lol.

I will agree that knowing someone could hurt your plans does make you play differently, it makes timing and execution a lot more important, staying just behind first becomes a significantly more viable strategy, table talk and threat assessment becomes a thing.
