I find it a bit unrealistic in a sense that I think Russia and China would not join - and possibly other dictatorships as well, making the case for them to “build their own -cut off from the rest of the world - internet” (https://codastory.com/news/russia-sovereign-internet-law-passes-2nd-vote/) even stronger. Yes, it is already happening, but if you’re asking them to pay for the internet of all, they’ll probably turn their backs?
And, I think that’s really not great for the people living in those countries. So, rather helping the world, it could be having the opposite effect.
But - hypothetically - I am totally for it. And if we’re ok with a divided internet - sure. But i’d personally rather see China remove the walls they’ve already built around their internet. And, at least now citizens can get around things and access content they want to, but this may become quite difficult if it’s pushed more behind walls.
