Anonymous speech is always the last refuge of freedom of speech. You can have that anywhere, it doesn't require a "free country".

thats observably not the case: countries where the government is unopposed in speech censorship do it pretty well. the only way people can engage in speech banned by the authorities is to do so on platforms run by countries who dont care about what they want to say

Subversive speech can survive despite the efforts of a government. Foreign platforms are one option, another is posters put up at night or materials circulated hand-to-hand.

But it's true that it's going to be a lot easier to remain anonymous when your opponents don't have the resources of a government.

Let's be honest nobody really cares about your opinions real name or not. The point of posting on the internet is to get something off your chest.

You can also find a like-minded group of individuals on the internet who you can discuss your beliefs with.

I mean, that's the point. People care what RMS has to say in part because of the work of the FSF. Work other people are doing shouldn't necessarily amplify his stupid opinions.
