The airline industry is heavily regulated and the software industry isn't. Will Boeing be punished if they're found to have made a mistake - politically it's an absolute certainty, legally I presume it'd depend on whether there was an element of knowing to it, or whether all parties genuinely believed they were doing the best thing for safety.

But despite how tempting it is to punish people who make mistakes, it's generally understood that incompetence is not illegal and should not be. Criminalising incompetence just makes everyone a criminal and hands absolute power to prosecutors and regulators: a scenario warned against many times by students of history.
