Ah, I get what you mean here.
If the survey is asking how likely you are to recommend and your response of "Not likely" leads to the survey ending, people will feel as though their specific reasoning is not important, which makes it feel like a "wrong" answer because "right" answers lead to further questions.
I get that! Surveys are targeted, so it could be that the person was looking for "what are we doing right?" specifically rather than a broad-scale, "How do you feel about the game?" kind of survey. I can see why people would begin to infer things from that. Broadly speaking, the forums are most often a place where people come to air their grievances and give critical feedback, so I see where a survey on good things would be wanted and an in-game survey is a good way to do that.
