Yep, I'm divorced and my minor son goes back and forth between his mother's house and mine on a weekly basis. I have a NF subscription and he is signed into my NF account over there on his xbox and the moment NF tries to extort additional money from me is the moment I cancel my subscription.

Just throw Plex onto a spare computer, NAS, or something like an rPi4.

I have 600 movies on my Plex setup and 10ish TV shows w multiple seasons.

I aint ever paying for Netflix/HBO/Apple TV/etc.

Come to the dark side
