>Today, the government cannot write censorship rules.

That actually was my point: the governments do write the censorship rules already and define punishment that you get for violating them.

Child porn is censored, for example. Here in Germany there is censorship laws against promoting national socialism or antisemitism.

Our democracies are structured in a way that legally prevents the legislatures to write censorship rules as they please and without good reasoning, and that is usually achieved by constitutional law guaranteeing freedom of speech to the widest extent possible, of the press, of assembly and of religion, and a division of powers and the mandate for those divisions to check each other. The courts but also multi party democratic systems, the press, voters and activists and protestors play a significant role in this.

While this system is not perfect, and there were and will be mistakes and abuses along the way that need to be corrected - which usually takes a lot more time than anybody likes - it is still the best we ever had and will ever get I think. The only real "alternative" we tried, that of a "strong" leader or oligarchic group of "strong" leaders was and is always a lot worse.

But now we moved a very significant part, if not a major part, of public discussion forums onto the platforms of private companies, and are now surprised that the "strong" leaders on top of these companies do not necessarily share our values or even the minimal set of values our societies as a whole agreed on, and make up and change rules as they please, without any real repercussions so far.

And not just that, they sometimes actively try to use their immense powers of content distribution and "moderation" to nudge discussion into one way or another. We already see these companies getting bolder in restricting certain topics all by themselves, be it around certain Corona related topics, be it to "fight white supremacy" ideology or other "extremism". And of course the companies started by censoring topics where reasonable people would most likely say "oh, those are dangerous or vile ideas by dangerous or vile people" [and then somebody brings up the Paradox of Tolerance to justify letting the companies reign free in those areas]. I am pretty much convinced that a lot of these are test balloons by the companies to see how far they can push the envelope right now before the momentary backslash becomes too much. And if we let them, then over time they will slowly push the envelope further and further for more and more control.

We and our politicians even help those companies to gain more power and control, by writing laws delegating policing responsibilities to the companies and by demanding the companies start policing more against misinformation, extremism, racism or and other of those -isms more and more. Not only is that a transfer of power, it's at the same time regulatory capture making sure any future competitors to these companies have it almost impossible to enter the market at all.

The first step on your route to doom is signing a petition requiring people to "provide id before making a social media account" (as is happening right now e.g. in the UK because some racists said some vile things about English football players), and then before you know it you end up with a "social score" system like in China, except it's the big companies maintaining it and regulating it and not even the (repressive) government.

Good intentions and all that...
