You can run Jellyfin as exe too.

Then how did you use Plex? Did you even RTFM?

If you are advanced enough to run a docker image with Plex, you can do the same with Jellyfin

No, you cant just „share processing power“

Also you could host something like a Lemmy instance, but then you had to get it federated, and mod it, and what not

If you want to do something good, host a snowflake proxy or something

Self hosting just means maintaining your own Instance of a web service instead of paying for someone else‘s

As long as you dont pay hetzner for an explicit fully maintained Nextcloud server, it dosent matter if the OS you‘re running it on is a VM or a bare bones server
