The Internet is great but broken. Back in the day, it brought us the Usenet Newsgroups, the Blogosphere and John Perry Barlow’s Declaration of Independence. Now, the Internet is dominated by monopolistic, addictive, asocial platforms that pit us against one another in a deluge of fake news, hate speech, disinformation and worse. Something has gone terribly wrong.

It suggests a shared and open sociotechnical infrastructure for pluralistic and federated platforms in Europe, and shows that most of the building blocks already exist. A different Internet is possible.
