Who asked them to build the ugly house (LCS)? John Q. Public?
Publicly call them out and let there be some accountability to ensure that that sort of monstrosity will never happen again.
Your comparison to private industry doesn’t hold much water. Company’s executives are accountable to both the BoD and the stockholders. There’s a reason turnover in non-government entities is so high. People get shitcanned if need be. And then they get to explain that to their potential new employer.
The MAX took a giant dump. Their CEO is out, albeit with a fortune. Maybe if senior leadership were held accountable they wouldn’t spend the taxpayers’ dollars so freely.
USN asked them to build the LCS via JROC process. John Q Public doesn't get a direct say in what programs the military decides it needs to accomplish it's mission. Love it or hate it, the requirements for what became LCS were approved by JROC and then the two versions were acquired to meet those requirements. LCS tried to do what so many people have asked for: it was disruptive and tried to do new things. That's how it was designed and we got what we paid for. Did USN overreach in trying to combine too many developmental programs at once? Arguably yes. But they to be aggressive to get new capabilities to the fleet.
To compare an Acquisition PM to a public company CEO is disingenuous. There's no profit expectation out of a PM. The PM just needs to do oversee the development of a program that meets the requirements. If you're looking for a CEO type equivalent it's CNO or SECNAV. But again, there's no profit there. And LCS us just one of MANY programs they're working. So to your Boeing analogy the LCS PM (or PEO as it is) is more akin to the PM for a large Boeing product such as the Max or KC-46. And let's be frank, in a few years we'll all be flying the Max. Boeing will get out of this and those jets will eventually fly. The solution isn't impossible, it's just bad for Boeings bottom line.
Plus, while the Boeing CEO took the fall, the board was most certainly involved in the decisions that led to the Max. Will those guys lose their jobs? Nope. Of course the CEO will, he's the organizational fall guy and CEOs know it. That's why they get paid so we'll because it's their head on the chopping block. And while the former Boeing CEO was fired, it's not like he'll never work again. He'll get a new job.
I'm sorry but this mystical pursuit of "accountability" for things that didn't go as planned has me confused. Everyone wants "accountability" but no one can say what that means. Should we get all the former CNOs up in public and throw tomatoes at them? Should they be drawn and quartered? Should they be blacklisted from all the cool clubs?
