They won't admit that, and you'll hear a lot of gab about algorithms and cooperation with various governments, but at heart it appears to me that this is cooperation with various governments as a government themselves. It's a negotiation among equals.
We can provincially argue about who can say what in the US on which platforms, or what the rules _might_ be to demonetize and/or kick people off platforms, but at the end of the day, the platforms themselves, through means mostly opaque to us, are negotiating as if they were our local tyrannical government with complete control over the public square and public places.
I understand that for many this is completely far-fetched and I'm making a mountain out of a molehill. This is a difficult thing to freely admit and grasp. It's also very difficult for those that are currently happy with whatever the most recent decisions are.
Yes, the net is still (mostly) free and open, and competitors _might_ come along and take the place of the current major social networks, but at heart this is a problem based on generalizing and universally abstracting social interactions. You could split up and/or dismantle every major player today and be in the exact same spot five or ten years from now when the next ones come along.
I am happy that more and more people are finally waking up to the danger here. If we are allowed to adequately describe the nature of this problem, we might have a shot at fixing it.
