The idea is to keep it simple to push the control balance from the geek to the users. To use existing tools to build a open network then let the users decide how to use it. This is the “news” part of indymedia the privacy focused actavist part is needed as well. Plugging in tor and scuttlebutt provides that side. In the end its just human moderated flows and actually technologicaly neutral, anything can be hub/peer on the network. Its just like the underlining tech of the internet and web itself.
Simple. And if you look at the fedivers all this already exists.
