Now you say even unethical corporations normally kill much fewer people than unethical governments. Which is true. But I have to ask, why do unethical corporations kill so few people? After all, they're all led by the same greedy people. It's not like CEOs magically become conscientious and say "Well, we can make billions of dollars by screwing all these poor people, but fuck it if we end up killing them!"
The answer: governments. Governments keep corporations in line so that they can't get away with killing people. Where a government is run by better people, corporations tend to not kill people, because they'll face consequences.
So, you are right that an incompetent government can be much more dangerous. However, one way such a government can kill people is by colluding with corporations and voluntarily relinquishing its authority (and duty) to police them as a government should. When you're limiting the government's power over corporations, in some situations, you could be in fact ensuring that the government remains incompetent.
There is active push back from a whole host of multinational megacorps for any relatively toothless threat represented by todays FCC what should concern you is that those same forces are actively largely ok with the real existential threats to freedom on the internet today.
But I digress -- in any free society people will eventually cause horrible things to happen, it just seems to me that the government inevitably causes much worse things to happen.
