The inability to use force doesn't make corporate power any less powerful--it only makes it a different kind of power. Yes, BigTech cannot arrest me or throw me in jail, but that doesn't mean that they don't wield other kinds of enormous power over my day-to-day life.

And unlike my (technically democratically elected government), corporations do not have to answer to the people they exert their power over.

I'm not trying to say that big tech doesn't have any sort of power at all that significant, of course they do. They certainly have a lot of control over information and how it shared. But I think that is unequivocally a lesser power than being able to imprison someone or put them to death. The fact that some small number of government officials are elected might be a rationale for that power, but it doesn't decrease it in any way.
