A company will always err on the side of firing an employee when threatened with a lawsuit or government action. The principle behind this behavior is very simple: make sure the finger is pointed at the party least capable of fighting for its own rights.
It's anecdote time using this throwaway account.
I used to work as a software engineer at a major hedge fund, where most of the computer systems were run by an outside vendor. One of these systems was a Flash-based data tool, an archaic piece of work that was poorly implemented, entirely undocumented, and thoroughly hated by everyone at the firm. I was part of a three-person team who, along with the CTO, were hired to replace this website. We were told to use whatever means were necessary to figure out a way to build better systems for the hedge fund.
On a fine summer afternoon not so long ago, my teammate was trying to figure out how the existing Flash-based website worked. This person downloaded a popular Flash decompilation tool in order to peek at the UI source code. Neither him nor me were aware that the same vendor who ran this Flash-based website had also installed surveillance software that pulled web browsing history from every computer at the firm.
It turned out that the firm's contract with this vendor included explicit verbiage that prohibited any kind of reverse engineering of the Flash-based website, and specifically called out Flash decompilation as a forbidden activity. Obviously, none of the employees were ever notified of this clause in the contract, and were unaware of the forbidden nature of this activity.
A few days later, the entire department - the "offending" colleague and two other engineers including myself, as well as the CTO - were all summarily fired for violating a contract clause that none knew about.
This man's story is sad and regrettable, yet it does not surprise me in the least. The firm screwed up, and chose to take a course of action that limited its own responsibility at the expense of four livelihoods.
Sic transit gloria mundi, while American greed continues on its own vicious course.
