I think there's a big reason why 'free speech' is being so heavily touted at the moment and of course there is the reasonable backlash to heavy policing of speech by those on the left of thing that they disagreed with that they instead claimed were harmful. But the calls for 'free speech' also benefit those who wish to spread lies unhindered.
When it comes to MN, which is the social media platform I engage most with, I would previously have been of the opinion that lies and false information should be rigorously challenged rather than deleted, to educate people etc.
But during covid there was a massive influx of false information about the vaccines, and clearly, during a pandemic, this is a huge health and safety issue. I'm not talking about reasonable concerns about side effects or whatever but 'vaccines give you autism' or 'vaccines are going to be used to control the population by killing off half of them' or 'vaccines are implanting a microchip into you' or even 'vaccines are the tool of the Jewish elite who control the world and we are headed into melding with robots' (yes really).
And people were challenging. And you'd report it to MN and they'd say 'we note that it is being challenged on the thread so we will allow it to stand'.
But it was overwhelming. And people were getting tired of challenging, and just giving up. And I think MNHQ realised that there was a genuine problem and started deleting these threads and posts that were deliberately spreading misinformation which, I think was in that scenario, the better solution.
