Why do you want to host them? Usually the difficult parts are necessary because they’re needed to have the level of control, security, and privacy that is the reason a person is self-hosting in the first place. And there are not enough simple standards for running software securely so you do need to learn some nerd stuff to do it right - but no so much that it is impossible for a beginner.
This is already in blue cities they just use it against BLM and pro-Palestine organizers.
Fascism is a consequence of capitalism. Free (or very cheap) energy would not end capitalism outright, it would just reduce a cost in how profit is made.
The only hope for our collective future is socialist organizing. I highly recommend that anyone interested begin reading about the topic using books written by socialists and by joining a socislist organization or attending their events.
For academia I recommend having an IT cost center responsible for the hosting infrastructure, namely virtualization. Then let people have VPSes (or similar) as needed to run docker-based services. This makes it easier to handle network and security concerns. Most large universities already offer something like this to students and faculty.
