@okpierre @evan @Mushi the license you pointed at concerns the distribution if the at protocol reference implementation. The propietary character of the protocol itself is a different matter.

@okpierre @evan @Mushi but that's not how openness works for network protocols. Governance is critically important.

@evan @Mushi it seems to me ATProto’s descentralization is mostly theoretical (it is not realistic for a person or a small organization to run the main aggregator service and indeed no one but bluesky does) whereas for ActivityPub is not only possible but a reality.

If Bluesky were to dissapear today, all the self-hosted PDS instances would be rendered useless immediately. If Threads or the biggest mastodon instances closed today, the fediverse would still be alive and kicking.

I just finished a first read of @evan ‘s ActivityPub book from O’Reilly. The definitive guide for anyone who wants to write applications for the fediverse, imho. The detail level is spot on.
