The question is poorly worded as it's not clear whether you just mean "Does Medium itself have an association with poor content that creates a stigma" or whether it would also include reasons such as "I don't click Medium links because of the paywall or bad UX" Strictly speaking it sounds like you're asking the former but the latter is the reason I don't tend to read Medium content. I would argue that this kind of ambiguity means your results are probably worthless. (On the whole I find most surveys suffer from an issue like this)
