One thing that is missing from much of the unthinking #mainstreaming outreach and expansion is that the history of #ActivityPub and the #Fediverse is a grassroots collaboration, and an ongoing struggle between open and closed paths. To understand this history, we need to explore the origins of ActivityPub and its evolution within the broader #openweb movement.

The roots of decentralization, ActivityPub emerged as a response to the limitations of early social media protocols like #OStatus, which powered platforms such as #StatusNet (later GNU-social). While OStatus enabled some level of federation, it lacked robust privacy features and limited conversation dynamics. This pushed developers to seek alternatives that could better support native social interactions.

The early drafts of ActivityPub, initially called #ActivityPump, were an ambitious attempt to build a flexible protocol supporting rich, decentralized communication. Unlike OStatus, which used XML, ActivityPump adopted JSON, a more modern, lightweight, and developer-friendly format. This shift made it easier for platforms to adopt and extend the protocol.

The transition to ActivityPub, the move from ActivityStreams 1.0 to ActivityStreams 2.0, and ultimately to ActivityPub, reflected the need for a more comprehensive standard. ActivityPub introduced server-to-server communication, enabling platforms to share activities, like posts and follows, across different instances. This innovation laid the foundation for true federation, where separate platforms could interact seamlessly.

Key projects helped shape this evolution. Pump.io, created by #EvanProdromou (the developer behind StatusNet), was an early experiment with ActivityStreams, though it never achieved widespread adoption. But these experiments were stepping stones that informed the development.

Next is the role of #Mastodon and the rise of the #Fediverse, Eugen Rochko’s decision to implement ActivityPub as Mastodon’s primary protocol catalyzed the growth of the Fediverse. Mastodon offered a #openweb “native” but familiar Twitter-like experience with federation baked in, its rise attracted a wave of people disillusioned by #dotcons social media.

As Mastodon grew, other platforms joined the ecosystem, #PeerTube for video, #Pixelfed for images, #WriteFreely for blogging, and meany more. Each new platform enriched the Fediverse and reinforced the strength of a decentralized path.

There are challenges to openness, despite its successes, this journey of rebooting the #openweb with ActivityPub and the Fediverse hasn’t been without friction:

• Commercial Capture: As the Fediverse gained traction, larger players began exploring it. #Threads’ integration with ActivityPub, for instance, raises concerns about whether the #dotcons might dilute the Fediverse’s grassroots ethos.
  
• Technical Complexity: Implementing ActivityPub isn’t straightforward. the pushing of features like HTTP signatures for verifying interactions introduce technical hurdles that can create compatibility issues between platforms.
  
• Centralization Drift: Even within the Fediverse, centralizing tendencies continue. Mastodon’s continuing dominance has concentrated influence, raising questions about how to prevent decentralized paths from replicating the “common sense” patterns of the #dotcons.

There is a constant need for guarding this open future, in which we need to balance the outreaching to the #mainstreaming with caring and supporting the native grassroots that created the value in the first place.

Looking forward, the future of ActivityPub and the Fediverse hinges on collective action. We need to resist the “common sense” commercial co-option from both friends and enemies to expand into building tools that make decentralized tech more accessible #OMN

The promise of the #Fediverse isn’t simply technological, it’s cultural and political. It’s about reclaiming the internet as public commons, where communities thrive on their own terms. On this path, by staying rooted in collaboration and community care, we ensure the Fediverse remains a beacon of hope in increasingly enclosed digital paths.
