Really? The only negative effects I've heard of were the "popcorn lung" from unsafe additives and obviously too much nicotine. Do you have a link?
True, but at least vaping isn't going to hurt you like secondhand smoke, and vapers don't throw butts on the ground.

I don't think jellyfin does any tagging for you. Pretty sure you can edit it, but it's not automatic. I use lidarr and mp3tag for that. Maybe musicbrainz picard on a rare occasion, if I've got a bunch of files that need to be identified first.
Yeah, but then you're not self-hosting, you're paying or using their free services to manage that for you.
You can cast jellyfin to any receiver. I use a Chromecast. Hearing people think they need an app just to use their TV as a TV is painful.
Yes, unless it lets you list exceptions, that would defeat the point. You might need to set up a full router and firewall.
There was a time they respected it?
