I think this is a cultural difference between security people and large populations of ordinary people. Security people tend to know both that breaking into something is generally possible if you put enough effort into it and that corporations are full of little napoleons who will try to curse your entire family for five generations if you embarrass them in public. And then "never affront the lawnmower" becomes a cultural norm out of self-preservation.
Whereas for ordinary people, even in tech, seeing a security lapse is often met with some combination of cynicism and schadenfreude and "LOL" seems like a pretty normal response.
Also notice that you're reading the company's version of events, which is naturally casting this exchange as a conspiracy against the company rather than the former employee reporting the security lapse to their contact who still works there who should have passed it up the chain -- but might not if they're afraid of sticking their hand in the lawnmower.
Meanwhile I have trouble feeling outrage at this sort of thing because I don't think legal protection of trade secrets is a good policy. Competitors have a moral obligation to uncover things like this to increase competition in the market and if the company wants legal protection for its technology then it should file a patent (which will subsequently expire to the benefit of the public) rather than expecting public assistance for its attempt to sustain a monopoly rent forever.
