Mastodon is the Linux of social media. The UX needs a little work but the momentum behind the project might help it overtake the other proprietary platforms.

@kelseyhightower also tempted to run mastodon on k8s, and the cool thing is that mastodon has helm chart: https://github.com/mastodon/mastodon/tree/main/chart
