independent media would probably do well to look at independent infrastructure. owncast[1] is an interesting project (no affiliation), I’d be curious if there are more like it.
The fact that an "independent infrastructure" project gets referenced by linking to GitHub should tell you everything you need to know about the state of "independent infrastructure" in 2021.
It’s not that it’s so hard to set up Redmine, just again that GitHub has strong network effects and a lot of convenience. I can go star stuff and come back later. Bookmarking a random open source project that self-hosts and hoping it’s still there when I need it is less convenient.
