I'm most familiar with the American context where we do have a degree of immunity. It was under the Communications Decency Act, and it was designed to give us the flexibility to implement our terms of service so that we wouldn't get sued. America is a very litigious society, as you know, and that protection has enabled us to create and maintain a much safer platform than it otherwise would be.
What you've seen across this table and across the world are many different regimes trying different mechanisms to do that. There has been independent research about the implications of that, including places where accusations were that the platforms overcorrect and squelch good speech. In the U.S. we don't often get criticisms from government to take things down because it is a violation of our hate speech or hateful conduct policy, but rather because it is a violation of copyright law, because the copyright rules in the United States are very strict, and we have to take it down within a certain period of time.
Rather than taking somebody who is critical of the government and asking them to take it down because of other terms of service, they go to the strictest regime, and that has a very negative impact on free expression.
