I think the point was that the fault may lie in the poster on HN and not the author of the survey, provided they're separate individuals.

The questions and candidate answers themselves are also heavily biased. The survey is clearly not intended to be an unbiased scientific poll.

Sure - either way it's not a "fair" survey. If I were making this survey trying to be scientific and somebody posted it to HN with this title I would be quite upset at them for priming a large number of my participants.
