>Twitter should be a public utility like water. It shouldn't rely on surveillance capitalism to make money. There's another social network called Ello and it's essentially a registered charity. Twitter should be like that.

A charity? Sure, if you can make it work. But a public utility? That would link it to governments, which I think is the last thing we should be pushing. I think there is already enough concern over how Twitter interacts with governments, especially those looking to censor speech. https://en.wikipedia.org/wiki/Censorship_of_Twitter
