I have been interested in "decentralised", "open", or "federated" social networks since my teenage years. These networks include software such as Mastodon, Pixelfed, and Bluesky, as well as to some extent Meta's Threads. In contrast to existing platforms such as Facebook and Twitter (X), users can more easily leave platforms without being cut off from the rest of society, as services on the "open social web" co-operatively talk to one another. This is very similar to how email functions: I can send a message from my ed.ac.uk address to your outlook or gmail address. User choice would put market pressure on social media companies to provide better services, avoiding the infamous "enshittification" of platforms.
