Centralization and decentralization of the Internet

Mastodon is divided into groups, called servers, based on many topics including the UK, snooker, and security.

Twitter has blocked links to some of the largest servers which users would join, including the most popular "social" channel.

And Twitter is also stopping users from adding links to their Mastodon account in their bios - calling them "malware".
