@cy that is cynical take. Maybe warranted for some W3C open standards, idk, but the authors of #ActivityPub are fedizens that have spent blood, sweat and tears and countless hours volunteering for the community and the commons to help make the #Fediverse what it currently is.
It is now time for others to take over and bring the fedi to a higher level, building on what was established before. This is a problem as most people work on their own apps, less on making the ecosystem more accessible.
