They didn't beak the law any more than assemblers in the pinto plant broke the law why installing the low strength springs in the ignition. It's the designers/coroprate decision makers who broke the law.
Even in the Pinto case nobody went to jail: An Indiana grand jury indicted Ford on three counts of reckless homicide — a landmark moment as the first time a corporation had ever faced criminal charges for a defective product, and the first time a corporation was charged with homicide. The charges stemmed from the deaths of three young women whose 1973 Pinto burst into flames after being rear-ended. An Indiana jury found Ford "not guilty" after a 10-week trial. Even if convicted, the maximum fine Ford faced under Indiana's 1978 reckless homicide statute was only $30,000. The company as a whole was charged with criminal conduct, but no actual executives stood trial. The prosecution targeted the corporation as an entity, not Lee Iacocca or any of the engineers or managers who made the cost-benefit decisions.
Ford as a corporation was found civilly liable and paid out in well over 100 cases. No individual executive — not Iacocca, not the engineers who ran the cost-benefit analysis, nobody — was ever personally named as a civil defendant in a judgment.
The Pinto fiasco produced massive civil liability and a historic (if failed) criminal prosecution of the company, but not a single person ever faced personal criminal jeopardy for it.
you may feel wronged by the whole thing but the grinder didn't do anything to you legally.
