Authoritarianism (or vertical/hierarchical power structure) is THE defining characteristic of the right. “Auth-left” is Doublethink; an oxymoron meant to distract from the fact that wealth and power are one and the same.
This is so incredibly naive. Stalin? Mao? Evil authoritarianism comes in all flavors left and right. If you truly believe leftists aren’t capable of evil you need to study more history.
I think you are definitely getting into overkill territory here with a server rack dedicated to Plex and a GPU. Most igpus on Intel chips can transcode 10+ 1080p streams and 2ish 4k streams. Unless you have 100 users seems over kill to me.
Edit. I’m on Unraid with about 30 users, and I only give Plex and all my other containers 6 cores from an i7 10700k.
