Great points! I remember that in uni they made a huge point of making sure we understood how to create surveys and undertake interviews so that when we designed them, our questions didn't lead respondents to a specific response or rationale. That would ultimately make at least some of your survey results inadmissible. For example, in the example you gave, nobody would pick the last choice because the rationale is phrased in such a way that it feels damaging to one's reputation - almost as though they aren't community-minded (which, depending on the society the respondent lives in, could be a huge no-no). So, naturally, the survey designer has led them away from that response.

So at the end of the day, what you had to do if you wanted to let everyone give them honest and detailed reasoning - and have more accurate results - is to create other questions that people can actually respond to in free-form. But that means more work afterwards, and you'd have to sift through all the responses and create categories for them to be able to analyze them statistically, and a lot of people are just too lazy to do that, I suppose.
