That's because there's no feedback loop of what you're saying, in the active lives of the people interfacing with GitHub. Consider an example of ingesting poison. If the poison tastes bad, I'll be sure to spit it out immediately, either by involuntary disgust, or because I associate with that negative feeling of being poisoned, something I don't want, so I react. But what if the poison tastes good? And what if it not only tastes good, it actually rewards me for ingesting it, in some way? People tell me it's poison, it might not say so on the label, and many are also ingesting it. Is it even believable that it's poison, given that I don't experience the negatives at all?
