>1) Do we really want social media corporations arbitrarily deciding which countries' citizens have an online voice?
Sure why not?
>2) Isn't it possible that allowing everybody from a "hostile" country onto Twitter will spread dissenting ideas faster? There's a reason that North Korea, as an example, basically doesn't allow most of their people any outside Internet access.

The thing about despotic countries with dictators. They don't really care about free speech. In fact, you had greater free speech in syria than you do in canada in say 2005. The dictator keeps their people in order by threat of violence knowing their opinion is poor of them. Whereas in Canada, nobody is shooting civilians. So the canadian government is forced to have compelled speech and anti-speech laws and extensive secret snowden level surveillance to keep the peasants in order.
If you read elon's post to 'advertisers' this post was absolutely not to advertisers. It was to the government to say they get to keep their interface.
