I don't know why everyone in the selfhosting community still even mentions Plex or uses it.
It's closed source, not free; Jellyfin is a no brainer yet people still go to Plex??
I would switch in a heartbeat if Jellyfin didn't... kinda suck, honestly.
But the difference in usability is enough that it's just not an option.
For the record, I updated Plex today and I haven't seen a notification like this anywhere, although that text snippet does match their privacy policy ad data opt-in settings blurb that has been in place for a while. I may need a bit more context here.
Only issues I've had with Jellyfin are reduced flexibility in naming/organizing files and inability (for me at least) to detect personal media.
There should be a library type called "Home videos and photos" for that.
I probably made a small mistake in setting that up but I tried making the dedicated "home movies" folder and it wouldn't show my videos.
