First " since he has clearly expressed he doesn't believe in pre-emptively censoring anyone just because their views are not aligned. "

This is completely false. Nobody is barred from Twitter pre-emptively, and nobody is barred because their 'views are not aligned'

More importantly, it's naive to believe that the commons can decipher the truth.

They cannot - neither can you or I - in a world of total disinformation.

The 'truth' does not rise to the top, rather, the ideas that are the most seductive, that appeal to our impulses and beliefs, are the ideas that rise to the top and especially if there are potent interests - and there always are i.e. Economic or Political, that 'free forums' will be controlled by those interests which will likely have nothing to do with any kind of 'truth' - which is in the public good.

People are busy, and the world is complicated - so we need centres of credibility.

For example - Doctors and Medical Information.

That's a hugely regulated sector, because we don't want Yahoos selling you 'Cures for Cancer' when they don't work at all. And there would be a Trillion dollar business there, if were allowed, causing untold harm. We already have a lot of problems there actually.

There is no 'free speech' in Medical Information.

I'll use your own example against you:

Do you think that Europeans are magically smarter than Russians? How is it that large number of Russians, even those who technically have access to 'outside information' come to such a deluded view of reality established by Putin?

Why do you think that Europeans are going to magically enlightened and not susceptible to his made up reality?

Putin has not 'cut off' Russia, he just needs to raise the barriers a little bit (i.e. VPN), because most people will just watch the propaganda otherwise.

That way, he can create a 66% buy-in in Russia.

If he can aggressively drive his misinformation into Europe, he could create a 15% support, and maybe 25% disinclination, enough to tilt the tables in many political situations, based on complete fabrications.

In the Weimar Republic, Stalin had direct control over 17% of the Bundestag via his direct control over the German Communist Party achieved through control over popular information ie propaganda in the commons.

30% of the USA public believes that the election was stolen, which is a lie.

If you take a survey among progressives about police violence against African American and ask them to put some numbers down (i.e # of unarmed African Americans being killed by police) - you'll get outrageous answers, not really based on any kind of reality.

And both of those things are problems even in the current system which has 'some integrity'.

All un-moderated public places turn into chaos very quickly - that's the first problem.

More importantly - they will be used by forces to create the reality they want.

It's fine to have a view of what Twitter should and should not be of course, if you want Elon there, that's great.

But nobody who is not a Twitter investor should really care that much about 'fiduciary responsibility'. The 'Truth' is a much, much more important public good that some random guys economic interest.
