@cstanhope i understand that more or less is the same for every service that you do not run yourself. I'm a guest i have to respect the rules of the owner/,manager/admin , if i don't like the rules i need to find another place . At least they are benevolent :-)
On mastodon there is sunbeam.city that was inspired by social coop.
Outside mastodon theres a few platforms run by cooperatives of user/owners. #platformcoop
Plus there are #coops which have set up platforms for use of their members, but where the #coops purpose isnt the platform.
eg. https://community.coops.tech/ - its also open to people who are not in the member coops (its a coop of coops). So for them coops.tech is a benevolent dictator.
social.coop is a a coop-run corner of the fediverse, a cooperative and transparent approach to operating a social platform. We are currently closed to new memberships while we improve our internal processes and policies, and plan to re-open to new folks when that work is complete. [9/2/2018]
