How does one create a thing and then lose the moral right to destroy said thing? That's not something I think you'll be able to justify to me. Just because it's destruction may hinder other people doesn't mean that it isn't the creators right to do so.
When other people's livelihoods depend on the thing you created, you lose the moral right to wantonly destroy it. When what you built stops being wholly yours, you lose the moral right to wantonly destroy it.
I agree once over 50% ownership has transferred you lose the moral right to destroy it. I should have clarified and said the one creates and owns, or even just owns really.
I disagree with the other assertion that you lose the moral right to destroy it. Does he have the moral right to fire his employees? I hope you'd agree with me that he does. And in this case he'd just be firing all of them.
It's not about math. It's about responsibility, both in the case of ownership and in the case of people depending on you.
You asserted that he has a moral right to destroy the company because he built it. He might have built it, but it doesn't matter if he now owns 54% or 90% or 10% of it, it stopped being just his. He can't just say "screw it, I'm bored, let's just burn it down to the ground".
That responsibility is even greater when it comes to the people who depend on you, who put their livelihood in their hands because they believe in your company. Not necessarily in you, but certainly in what you created.
Let me put it this way: if you knew that the person in charge of company X is a volatile, irresponsible person incapable of putting the good of the company before their own ego, someone who doesn't care enough for the company, would you go work for that company?
Musk's behavior is damaging the company. His employees are objecting to that, among other things. They are right to do so.
As for whether he has the moral right to fire his employees indiscriminately solely by virtue of having created the company? No, he doesn't, for the same reasons I described above.
Does he have the right to fire his employees for the right reasons? Of course, but that's not the case here. That's what I was pointing out when you asserted that he certainly has the right to fire them just because he built the company.
Looks like we're at an impasse as we just fundamentally disagree. Indiscriminate should be federally legal and fortunately is in many states. I believe he every bit has the moral right to fire indiscriminately and burn his company to the ground if he wants while he retains majority ownership.
