Re: Difference between authoritarian governments not a social media companies
This is not hard. Social media platforms have traditionally allowed you to say basically whatever you want so long as it's not detrimental to other people's ability to use the platform (e.g. spam) and doesn't break certain basic laws (e.g. no actual threats, no CP) or community standards (varies by platform). For example, YouTube and Reddit have a history of defending the speech of their users to a fault, even getting into trouble with governments (and broad swaths of the public) for it. If you want a specific example, you can see the case of Anwar al-Awlaki, a terrorist that YouTube resisted taking down videos of until significant pressure mounted from the US and UK governments in 2010. Twitter pre-Musk also resisted Turkish censorship (2010s), leading to the site getting blocked rather than cave to Erdogan's demands.
I'll admit that western social media is no longer quite as rosy on this point as it once was (for many reasons, some good and some bad), but they're certainly miles better than authoritarian governments.
