Yup, but of course more than one person has to agree for this to actually happen. Which is not the case for other apps, like Twitter/X. If Musk wants to remove a government, he has only to promote "free speech" and let falsehoods and misinformation dominate his platform.
> even among humans there is no agreement
This is just not true. There are objective facts eg. the earth is round. We can all agree on this, and any information to the contrary should be banned.
The majority of us agree that racism is bad for society. Racist content should be banned.
Yes there are always going to be humans who think the earth is flat or has a core of cheese, but these people can be relegated to the fringes of society.
geopolitics aside could a turing machine identify misinformation / programatically check whether something is true or not? because even among humans there is no agreement
