You can run software on bare metal without an OS. The downside is you have to write everything. That means drivers, networking code, the process abstraction (if you need it), etc.

One thing to remember is an operating system is just another computer program.

You would end up blocking every network then. Almost no one wants malware on their machine or network. Unfortunately, people get hacked and network operators cannot always determine which machines are hacked (hackers are not known for letting people know that they have taken over a machine).

Security is hard and there are no easy solutions. People often do not know they have been hacked or even know if a computer on their network has been hacked. Also, it is often not easy to determine if traffic is legitimate, illegal, malicious, or abusive.

Wire-fraud is a United States legal concept. It's probably not applicable to Germany (although Germany might have its own laws which cover this issue).

I wish these companies luck. That being said, I would not recommend working all of the time to almost all people. Here is why:

1. According to Rapid Development or Code Complete (I can't remember which book said this), for most people, working more than 40 hours a week does not increase productivity in the long term. Basically, you can spend more time at work but you will not get more done. There are a few people who this is not true for but those people are rare and they usually are extremely driven because there is something about the project is really really interesting to them.

2. I strongly suspect most humans are just not built to work all of the time. It's not that there is something wrong with them, they just can't deliver more than about 40 hours a week of work. This isn't because they aren't committed, don't care, are lazy, etc. They just can't do it. I think this has to be accepted.

3. I have tried for decades to make the live at work lifestyle work and I have failed. I have repeatedly burnt out. It has taken me decades to realize that it is not a question of what you want to do, it is a question of what you can actually do and what is sustainable. Basically, you or your boss may want you to work 60 hours a week for months on end but that is probably impossible and it's better to accept reality than to keep on trying to do something which does not work.

Note that when I hear employers demanding crunch time, it tells me the leaders do not understand how people work because they don't understand that 99% of their employees probably cannot given them any more than they are already giving. This means crunch time does not improve productivity, but it does make everyone on the team more miserable because they are spending too much time at work and they are wondering why they can't seem to force themselves to get more done.

I am not sure what your point is. If Boeing went bankrupt, someone could buy them and the company would continue running. Also, Boeing is not the most important defense contractor in the US. They don’t make the F35 and they don’t make the new B21 Raider. The world is not going to end if Boeing disappears.
