Sure, that might have been the "trigger"; but that's missing the key thing that needs to be explained. If this were dishonesty by someone doing chemistry, it's unlikely that this would have hit the front page of HN. As they say, "Dog bites man isn't a story; man bites dog is."
But a priori, you'd expect someone studying honesty* to personally care about honesty, and thus to be less likely to give in to these sorts of pressures. That's the thing that needs to be explained; the "man bites dog" aspect.
