That’s a good thought and would probably work if I lived alone and only watched one thing at a time.
But I would say it depends on your use case and the size of your household. We are 4 ppl in my family that watch different content on the same TV at different times of the day. We have Netflix (the wife’s show is here), Disney (kids), HBO (me), Viaplay (family movies in my native language when we all watch together). I have been sharing thease accounts with my brothers family but we are about to move to Plex, I would rather buy DVD or digital releases and host it myself then use all thease subscriptions.
If they would price it better, could work together and all be used in the same interface on my tv then maybe I would be willing to go back.
