How about when they tell you to play ball or they're cancelling their contracts with you, which will ultimately destroy your company? (Similarly, when they insinuate that you'll receive contracts if you're compliant -- and your rival might if they're compliant instead.)
It's not (and has never been) do whatever you want with your company, once you reach a certain size. In fact, I don't think most of us actually want that. (Also, arguably, your comment section is a public accommodation and you're legally requires not to discriminate on certain bases.)
I'm not implying that the US is the same as China in this regard -- I'm pointing out that they US does regulate content in an authoritarian way, they simply vest that authority in private lobbying groups and exercise it via back-channel deals.
I find that worse than the open authoritarianism with an obvious source of blame, even if it's a "milder" authoritarianism in terms of effects.
"When machines and computers, profit motives and property rights, are considered more important than people, the giant triplets of racism, extreme materialism, and militarism are incapable of being conquered."
