Servers are just computers, you build what you are going to use it for. You can use a cheap N100 mini pc to host jellyfin as the important part there is the video encoder/decoder to transcode video. Though it can only do 2 streams at 4k with tone mapping. So it might not be good enough if you have more than 2 people using it or are running more stuff on it.

100% this. Not only did it kill 3rd party apps it killed moderators custom tools. I use to get notified that my post was removed and the reason why it was removed. Now everyone is forced to use reddit’s own tools and I don’t even get notified that my post was removed. It is super annoying when going to a new subreddit and posting for help/support just to go and see that the post was removed silently.
