I openly talk to them about it all the time.

I guess I was responding to this along with the content of your post.

I just don't talk about it and make it a point not to. I talk about what I'm watching. I talk about that my friends have requested shows/movies on the server that I ended up enjoying as well. I never talk about what they are watching or not watching.

I'm sorry if I got the wrong impression from your comments and post, but I just got the sense that you maybe brought up with them that you were sad that your friend didn't finish your favorite movie. If I were a friend with whom that was brought up with, I would think twice about what I pulled up on your server. That shows to me that my behavior is being watched and monitored, which isn't a great feeling, free service provided by a friend or not. Again, sorry if that's not the case here and you can disregard entirely, but this is just not how I talk to the friends and family about using my Jellyfin server.

It's not terrible. I would do the same as you before reading this post, and maybe I would after. I do think they have a point, though.

Mostly I'd watch it to see if it's being used or not.

Maybe Jellyfin could come out with an option to make things semi-anonymous. You'd be able to just click it off, but it wouldn't show you details unless you explicitly asked for them.

On the other hand, I'm very aware that if I were to use someone's Plex that their "payment" would be the satisfaction of seeing their service used. I wouldn't mind the stats they collect, but the fact that they collect them would be at the forefront of my mind.

I am sure my friend since the 3rd grade, my brother or my mother will be shocked at my behavior.

You'd be surprised. People get very antsy when it comes to what they think is a private thing. You're absolutely allowed to look at it, but understand that watching everything your users do is essentially traveling down the exact same road we are trying to avoid with big tech - watching, monitoring, and analyzing our data.
